An example:-

Find the final coordinates when the values K = 34, L = 28, R = 18 and S = 52

N51 L.R(5) W001 S.K(9)

Result

N51 28.185 W001 52.349

Straight forward and easy, but what happens when those four values do not have a fixed position? The answer is that you have a number of permutations. In reality it is not as many as you first think, but you are going to have to use your OS to finally define it. So with that in mind, if you want to find the murder weapon then solve this little equation using the values A, B, Y and Z you have already collected.

N51 (A or B or Y or Z). (A or B or Y or Z)(7)

W001 (A or B or Y or Z). (A or B or Y or Z)(5)

Oh, and to make it slightly easier, each value can only be used once.

Good hunting

Nearly there but not quite.
This is where it gets slightly complicated.
I am not just going to give it away!

You have to find 4 numbers, from the values that you have found so far.
Lets call them A, B, Y and Z.

A = D
B = E! + J + 2M
Y = H!/W + W
Z = LN - 500

Could not be easier.
I will tell you how you use the four values later.

A polygon with nine angles and nine sides is called a nonagon.
In French the word neuf means both nine and new. In German, the words for nine and new are neun and neu, and in Spanish, nueve and nuevo. As you count and reach nine, you know you are about to make a new start.

The game of skittles or ninepin bowling is many hundreds of years old. The pins are set up in a diamond formation and players throw the ball (or `cheese’) at them. In the nineteenth century some American states passed laws banning the game because bets were often placed on it. But these laws were evaded by the simple ruse of adding a tenth pin. As a result tenpin bowling is now the far more popular game.
The nine cubes on this Swedish stamp make an ‘impossible figure’. This arrangement cannot exist in the real world.
On cloud nine means happy, euphoric or `high’. The phrase came into use in the 1950s from a term used by the US Weather Bureau. For the meteorologists Cloud Nine is cumulo-nimbus cloud at a height of 10 km, which is high even by the standard of clouds.
Only about one ninth of the mass of an iceberg is visible above the water. Nearly all its bulk remains hidden beneath the surface.

The game of Shove Ha’penny uses a board divided into nine `beds’ or rows. The winner is the first player to place 3 coins into each bed.
It is easy to work out whether a number is exactly divisible by 9. This is the same as asking whether a number is in the `9 times table’. All you have to do is add up its digits. If the answer is more than one digit long, you add up the digits again, and go on doing this, until you are left with a single digit. If this single digit is 9 then the original number was divisible by 9.

Christopher Wren

He was Savilian Professor from 1661 to 1673 and he also occupied the astronomy room at Wadham. Had Wren not found his metier in architecture, he would have been better known as the brilliant mathematician and scientist that indeed he was. He excelled in geometrical demonstrations and Newton considered Wren to be `beyond comparison the leading geometers of this age'. About 1656 Wren solved a problem proposed by Pascal to the geometers of England and retorted by sending a challenge to the French geometers. The challenge went unanswered,

The Sheldonian Theatre was Wren's first large-scale building. It was started in 1664 and the official opening was in 1669. The magnificent painted ceiling, the work of Robert Streater, depicts "Truth descending upon the Arts and Sciences". Theology, with her book with seven seals, is imploring the assistance of Truth in unfolding it. Truth is sitting on a cloud in the middle. On the opposite side of the circle from Theology are the mathematical sciences; Astronomy with the celestial globe bound about by the Milky Way, Geography with the terrestrial globe, Arithmetic with a paper of figures, Optic with the perspective glass (telescope) Geometry with a pair of compasses on her left and a table with geometrical figures on it, and Architecture embracing the capital of a column.

Pieces of eight go with pirates and parrots. Originally they were piastre - Spanish silver coins of the seventeenth and eighteenth centuries marked with an `8’ because they were worth eight reals. The dollar sign $ is probably derived from the figure `8’ as it appeared on `pieces of eight’.
A cube has eight corners or vertices.
Many words beginning oct- are related to the number eight. An octopus has eight arms and an octet is a group of eight musicians. (An octet of octopuses would therefore have 64 arms between them.)
An octagon is a figure with eight sides and an octahedron has eight faces.

An octave is the interval in music between two notes where the higher note has twice the frequency of the lower. On a piano keyboard this corresponds to an interval of eight white notes, for example, the notes C D E F G A B C.
The term octave belongs to Western music, but the musical interval occurs in music around the world.
The amount of cloud in the sky is measured in oktas on a scale from zero to eight. 8 oktas means the sky is totally clouded and totally clear sky measures 0 oktas. A reading of 6 oktas would mean that three-quarters of the sky is overcast.

Paul Erdos, mathematician, died on September 20 1996 aged 83. He was born on March 26, 1913.

He was Phillip Oughtreds’ hero, he came to Oxford and stayed at Jesus College for a very short time. The photograph, which hangs in Oughtreds room, shows Erdos seated in the front row with a child on his lap and was taken in the colleges' quad.

Go to Ship Street around N51.45.246 W001.15.453 and look for something sheltering betwixed stone and iron, but the wall end. We will call this value E

Paul Erdos was regarded by fellow mathematicians as the most brilliant, if eccentric, mind in his field. Because he had no interest in anything but numbers, his name was not well known outside the mathematical fraternity. He wrote no best-selling books, and showed a stoic disregard for worldly success and personal comfort, living out of a suitcase for much of his adult life. The money he made from prizes he gave away to fellow mathematicians whom he considered to be needier than himself. "Property is a nuisance," was his succinct evaluation.

Mathematics was his life and his only interest from earliest childhood onwards. He became the most prolific mathematician of his generation, writing or co-authoring 1,000 papers and still publishing one a week in his seventies. His research spanned many areas, but it was in number theory that he was considered a genius. He set problems that were often easy to state, but extremely tricky to solve and which involved the relationships between numbers. He liked to say that if one could think of a problem in mathematics that was unsolved and more than 100 years old, it was probably a problem in number theory.

Erdos was born into a Hungarian-Jewish family in Budapest, the only surviving child of two mathematics teachers (his two sisters, who died of scarlet fever, were considered even brighter than he was). At the age of three he was amusing guests by multiplying three-digit numbers in his head, and he discovered negative numbers for himself the same year. When his father was captured in a Russian offensive against the Austro-Hungarian armies and sent to Siberia for six years, his mother removed him from school, which she was convinced was full of germs, and decided to teach him herself. Erdos received his doctorate in mathematics from the University of Budapest, then in 1934 came to Manchester on a post-doctoral fellowship.

Erdos had made his first significant contribution to number theory when he was 20, and discovered an elegant proof for the theorem which states that for each number greater than 1, there is always at least one prime number between it and its double. The Russian mathematician Chebyshev had proved this in the 19th century, but Erdos's proof was far neater. News of his success was passed around Hungarian mathematicians, accompanied by a rhyme: "Chebyshev said it, and I say it again/There is always a prime between n and 2n."

In 1949 he and Atle Selberg astounded the mathematics world with an elementary proof of the Prime Number Theorem, which had explained the pattern of distribution of prime numbers since 1896. Selberg and Erdos agreed to publish their work in back-to-back papers in the same journal, explaining the work each had done and sharing the credit. But at the last minute Selberg (who, it was said, had overheard himself being slighted by colleagues) raced ahead with his proof and published first. The following year Selberg won the Fields Medal for his work. Erdos was not much concerned with the competitive aspect of mathematics and was philosophical about the episode.

He would work furiously for a few days and then move on, once he had exhausted the ideas or patience of his host (he was quite capable of falling asleep at the dinner table if the conversation was not mathematics). He would end sessions with: "We'll continue tomorrow - if I live." After the death of his mother in 1971, Erdos threw himself into his work with even greater vigour, regularly putting in a 19-hour day. He fuelled his efforts almost entirely by coffee, caffeine tablets and Benzedrine. He looked more frail, gaunt and unkempt than ever, and often wore his pyjama top as a shirt. Somehow his body seemed to thrive on this punishing routine.

Because of his simple lifestyle, Erdos had little need of money. He won the Wolf Prize in 1983, the most lucrative award for mathematicians, but kept only $720 of the $50,000 he had received. Lecturing fees also went to worthy causes. The only time he required funds was when another mathematician solved a problem which Erdos had set but not been able to solve. From 1954 he had spurred his colleagues on by handing out rewards of up to $1,000 for these problems.

He died from a heart attack at a conference in Warsaw, while he was working on another equation.

7-Up is a soft drink. It was invented in America in the 1920s by Mr C L Griggs of Missouri who originally called it Bib-label Lithiate Lemon-Lime Soda. With a name like that sales were poor even though the drink tasted good and so Mr Griggs set about changing the name. After six attempts he came up with 7-Up, or so the story goes. 7-Up is also the name of a card game.
John Sturges’s 1960 western The Magnificent Seven is about a Mexican village that hires seven gunmen for protection from bandits. The story is based on an earlier Japanese film made in 1954 - Akira Kurosawa’s The Seven Samurai.
Ask a number of different people to give you any number between one and ten, and most will choose seven. Ask people to name their favourite number between one and ten, and again most will say seven.
In 1956 George Miller wrote an article The Magical Number Seven Plus or Minus Two: Some Limits on Our Capacity for Processing Information. This showed that the amount of information which people can process and remember is often limited to about seven items. One example of this is called the digit span.
Ask someone to repeat back to you exactly what you say. Begin with four digits chosen at random e.g. 6 6 2 5. Then give them five digits e.g. 5 8 4 5 0, then six, and so on. Carry on increasing the number of digits until they make a mistake. The longest number of digits they get completely right is called their digit span and for most people this is about seven digits.
Suppose someone is shown a pattern of dots for a very short time - just one fifth of a second - and they are asked to count the number of dots they saw. If the number is less than seven they will be right almost every time, but with more than seven, they will make lots of mistakes.

When times are mysterious
Serious numbers are easy to please

When times are mysterious
Serious numbers will speak to us always
That is why a man with numbers
Can put your mind at ease
We've got numbers by the trillions
Here and overseas
Hey hey, whoa whoa
Look at the stink about Japan
All those numbers waiting patiently
Don't you understand?

So wrap me
Wrap me

In the shelter of your arms
I am ever your volunteer
I won't do you any harm
I will love innumerably
You can count on my word
When times are mysterious
Serious numbers

When times are mysterious
Serious numbers will always be heard
And after all is said and done
And the numbers all come home
The four rolls into three
The three turns into two

1, 1, 2, 3, 5, 8, 13... A Fibonacci number.
We have five digits on each hand and foot. V, the Roman symbol for five, may originate from the image of a hand with the fingers spread.
Penta- means five. A pentathlon is an athletics contest with five events and a pentagon is a figure with five sides and five angles. A pentasyllabic word has five syllables, like the word pentasyllabic itself.
Pentagram, pentangle and pentacle are all names for a five-pointed star. This mystical symbol was supposed to keep away devils and witches. A pentacle headdress folded from fine linen was sometimes worn as a defence against demons.
A pentagonal bolt is fitted to many fire hydrants in the USA because it is impossible to undo with a normal spanner - most bolts are hexagonal.
A devout follower of Islam worships five times a day facing the holy city of Mecca. The Islamic creed is the `Five Pillars of the Faith’.

The Five Towns, made famous in the stories of Arnold Bennett (1867-1931), are the towns of Stoke, Tunstall, Burslem, Hanley and Longton in the Staffordshire Potteries. Bennett generated some ill feeling in the townspeople of Fenton, who were left out and claimed as much right to inclusion as the other five.
When you cut through an apple `the wrong way’ you get a five-pointed star. The wild rose has five petals. Apples and roses are part of a large family of plants called ROSACEAE which includes blackberries, raspberries, strawberries, pears, cherries, plums and peaches, all of which have five-petalled flowers. Although cultivated roses have many more petals, if you look beneath any rose, you will still find five sepals around the base of the flower.
The Five Platonic Solids are the only five convex regular solids it is possible to construct. They are the tetrahedron (four sides), the cube (six sides), the octahedron (eight sides), the dodecahedron (12 sides) and the icosahedron (20 sides).
Five was the lucky number for the superstitious French fashion designer Gabrielle `Coco’ Chanel. In 1921 she chose the fifth day of the fifth month to introduce her new brand of perfume which she called Chanel No. 5. At that time its scent was unlike any others in a market dominated by floral perfumes. It was a huge success and today it is one of the most famous - and most expensive - perfumes available.

The number four on a calculator is made up of four light bars.
Many things are arranged in fours. There are four suits in a deck of cards, four points of the compass, and four phases of the moon. There are four wings on a bee and four leaves on a clover, if you are lucky.
The four seasons are spring, summer, autumn and winter. This theme has provided inspiration for many artists, for the composer Vivaldi, and for countless take-away pizza establishments.
A tetrahedron is a kind of pyramid with four triangular faces. It also has four corners.
On maps adjacent countries are usually shown in different colours. What is the smallest number of colours needed? In 1852 Francis Guthrie guessed that the answer is four colours for any map, no matter what shape the countries take. No one has ever found a map that needs more than four colours. But it has been difficult to find a satisfactory proof that only four colours are needed. In 1976 Wolfgang Haken and Kenneth Appel claimed to have proved the four-colour conjecture, but their proof is so complicated, involving hundreds of hours of calculation by a computer, it has been very difficult for other mathematicians to check.
Tetra- means four. A tetradite is someone who attaches mystical properties to the number four. A tetragram is a word with four letters (like four itself).
Quad- also means four. A quadruped is a four-footed animal like an aardvark, or almost any animal for that matter.
Plus fours are loose baggy trousers which require an extra four inches of cloth in tailoring. This ridiculous male fashion was popular with golfers in the 1920s.
In a molecule of DNA, just four bases are used to make up the genetic code that determines the distinctive form of every plant and animal. The four bases are called thymine, adenosine, guanine and cytosine, or just T, A, G and C.
Four-dimensional means that something has an extra dimension as well as length, width and depth. For the scientist, this is usually the dimension of time, where space and time are thought of as part of the same continuum.
However, in mathematics, four-dimensional means an imaginary fourth dimension in space. With two dimensions you can draw a square and with three dimensions you can make a cube. But with four dimensions it is possible to represent something called a hypercube. Some mathematicians claim to be able to visualise four-dimensional space and can conjure up a clear picture in their heads of a hypercube, which they can rotate or cut in half.

Tri- means three. So triangles have three sides, tripods have three legs and the dinosaur triceratops had three horns. The French flag is a tricolore because it has three colours. Trigonometry is a branch of mathematics based on measuring triangles.
Three-dimensional means that something has length, width and depth.
There are three school terms in a year.

Once upon a time there were three little pigs ... three billy goats gruff ... Stories often begin this way and have a similar structure. Number one and number two are always similar so the listener is lulled into believing number three will be the same. But with number three there is a twist in the tale. In Greek mythology you will find Cerberus, a three-headed dog, and Scylla, a sea monster with six heads. It is curious that mythological heads are inclined to come in multiples of three.
If the number of petals on a flower is a multiple of three, it is probably from a group of plants called the monocotyledons which includes crocuses, daffodils, tulips, lilies and other plants grown from bulbs.
Most colours can be mixed from just three primary colours. But different primary colours are used for different purposes. For example, all the colours you see on a television screen are mixtures of red, green and blue light. With paint you can mix most colours from just red, yellow and blue pigments. The colours in books and magazines are usually printed from three coloured inks: cyan, magenta and yellow, although black ink is used as well.
We use three primary colours because of the way our eyes work. At the back of our eyes are cells called cones which are sensitive to coloured light. There are three different types of cone, each sensitive to different wavelengths of light. If our eyes were built differently and we had four types of cone cell, we would need to use four primary colours in printing, painting and television.

There is only one of lots of things. There is only one planet Earth, there is only one Atlantic Ocean and there is only one you. All of these are unique.
Words beginning with uni- often mean there is one of something. For example, unicycles have one wheel and unicorns have one horn. Unisex means the two sexes appearing as one because they are indistinguishable by hair or clothing.
The letters A, B, C, D, E, M, T, U, V, W and Y all have one line of symmetry.
A Möbius strip has one edge and one surface. It is easy to make by taking a long strip of paper, giving it one twist and joining together the ends. Ask one of your friends to colour one side of the strip red and the other side green. This turns out to be impossible because the strip has only one side.

Mono- can also mean that there is one of something. A monocle is an eyeglass with only one lens, and a monorail is a railway where the track consists of a single rail. Monochrome means using only one colour, like a black-and-white photograph. Chemical names often include mono-; for example carbon monoxide is a poisonous gas whose molecules have only one atom of oxygen.

The introduction of zero into the decimal system in the 13th century was the most significant achievement in the development of a number system, in which calculation with large numbers became feasible. Without the notion of zero, the descriptive and prescriptive modeling processes in commerce, astronomy, physics, chemistry, and industry would have been unthinkable. The lack of such a symbol is one of the serious drawbacks in the Roman numeral system. In addition, the Roman numeral system is difficult to use in any arithmetic operations, such as multiplication.
It is India that gave us the ingenious method of expressing all numbers by means of ten symbols, each symbol receiving a value of position as well as an absolute value; a profound and important idea which appears so simple to us now that we ignore its true merit. We should appreciate the grandeur of the achievement the more when we remember that it escaped the genius of Archimedes and Apollonius, two of the greatest men produced by Greek antiquity.
What is certain is that by around 650AD the use of zero as a number came into Indian mathematics. The Indians also used a place-value system and zero was used to denote an empty place. In fact there is evidence of an empty place holder in positional numbers from as early as 200AD in India but some historians dismiss these as later forgeries.
In around 500AD Aryabhata devised a number system which has no zero yet was a positional system. He used the word “kha” for position and it would be used later as the name for zero. There is evidence that a dot had been used in earlier Indian manuscripts to denote an empty place in positional notation. It is interesting that the same documents sometimes also used a dot to denote an unknown where we might use x. Later Indian mathematicians had names for zero in positional numbers yet had no symbol for it. The first record of the Indian use of zero which is dated and agreed by all to be genuine was written in 876. A problem which arises when one tries to consider zero and negatives as numbers is how they interact in regard to the operations of arithmetic, addition, subtraction, multiplication and division. In three important books the Indian mathematicians Brahmagupta, Mahavira and Bhaskara tried to answer these questions.
The brilliant work of the Indian mathematicians was transmitted to the Islamic and Arabic mathematicians further west. It came at an early stage for al-Khwarizmi wrote Al’Khwarizmi on the Hindu Art of Reckoning which describes the Indian place-value system of numerals based on 1, 2, 3, 4, 5, 6, 7, 8, 9, and 0. This work was the first in what is now Iraq to use zero as a place holder in positional base notation. Ibn Ezra, in the 12th century, wrote three treatises on numbers which helped to bring the Indian symbols and ideas of decimal fractions to the attention of some of the learned people in Europe. The Book of the Number describes the decimal system for integers with place values from left to right. In this work ibn Ezra uses zero which he calls galgal (meaning wheel or circle).
The Indian ideas spread east to China as well as west to the Islamic countries. In 1247 the Chinese mathematician Ch’in Chiu-Shao wrote Mathematical treatise in nine sections which uses the symbol O for zero. A little later, in 1303, Zhu Shijie wrote Jade mirror of the four elements which again uses the symbol O for zero
Of course there are still signs of the problems caused by zero. Recently many people throughout the world celebrated the new millennium on 1 January 2000. Of course they celebrated the passing of only 1999 years since when the calendar was set up no year zero was specified. Although one might forgive the original error, it is a little surprising that most people seemed unable to understand why the third millennium and the 21st century began on 1 January 2001.
Zero is still causing problems!

Want to know a few things about numbers do you?
Well this was something our dear departed friend was working on.

Well well well!
D S Lewis, two can play at this game. I have been following your career since that serial killer.You got there in the end, such a surprise as well.
Now lets see if you have it in you to find this so called murder weapon.
