THE LAST MISTAKE!
However hard we check there are always some copies that escape with a few errors. If you're lucky you might have one of the rare and valuable early prints of the book that claim on page 98 that 42÷8 = 6! On page 131, there is an extra "x5" under one of the square root signs, and page 124 features Reeve's 8 sided septagon. Sadly these have been removed for the later printings, but one lovely mistake remains on pages 49-50. Can you spot it?
To find the answer, drag your mouse between the # signs below!

THE PERFECT SAUSAGE and other
FUNDAMENTAL FORMULAS 241r6p
A useful reference book containing about 180 maths formulas for anyone aged 10 upwards
Suitable to help with exam revision from key stage 3 up to GCSE (and beyond) 3j5l5v
This book contains just about every maths formula you'll ever need ... and loads more that you'll probably NEVER need!
1p332h
As well as all the obvious formulas for area, volume, speed, acceleration and peculiar numbers, you'll get formulas for:
the area of a crescent moon
the lengths of snail trails round boxes
how many ways you can tear up a sheet of stamps
how long it takes for cannonballs to drop from great heights
exactly how much MONEY the bank should give you.
All formulas come with explanations, you'll find loads of different maths topics explained and there's even an INDEX so that you can quickly find any formula you want.
You'll also find out why the Pure Mathematicians get arrested, who sent Pongo McWhiffy a valentine card, what happens when 47 different alien races try to invade earth at once and of course the secret to the perfect sausage!

How This Book Came To Be Written 1s3r3p
Poskitt the author had a terrible nightmare that he'd missed some vital formulas out, so to make sure we included everything worth including, lots of MM readers and visitors to this site sent in their formula suggestions. Thanks to everybody whose name gets mentioned here!
All The Shape and Lump Formulas You'll Probably Ever Need 5d3q6h
The top twelve formulas are shown here, with a full explanation of how to use them if you're not sure. These formulas and many more are also available free on our Murderous Maths Wallpaper.
Numbers, Pizza Slices, and Alien Interpreters 4c62t
Triangle numbers, pentagonal numbers, centered hexagon numbers and so on... they might seem strange but they have a funny way of turning up in odd places, especially if you're helping Blade and the Gangsters chop up a pizza or if you're worried about an alien invasion.
Three different aliens need three interpreters - but how many interpreters do six aliens need?
Here's where the Pure Mathematicians end up in jail after trying a few high-speed experiments. After that you'll be testing acceleration by rolling down hills in a dustbin, pigeons will be testing gravity with a bit of target practise by the Eiffel Tower and Urgum the Axeman learns the wrong way to fire a cannonball.
Can You Feel The Force? 13333i
Isaac Newton explained gravity - and here's how to use it! But will it cause the terribly lovely Veronica Gumfloss to be attracted to Pongo McWhiffy? Pongo uses his shoe as a pendulum to find out.
MONEY! 1x321q
The Great Fogsworth Jumble Sale is under way, but who will make the most money? And when somebody leaves you �1,000,000 make sure your bank looks after it properly for you!
This is probably the most requested topic from the MM readers who ed us - how can you work out the day of any date in history? INT and MOD functions are explained, and the mystery of Pongo's valentine is solved.
Perms Coms and The Unknown Formula 4k5f1n
If you've read Do You Feel Lucky? you'll know about probability. Here are all the formulas you need whether you're throwing dice, arranging the gangsters in an identity parade or choosing a revolting mixture of paints for the Pure Mathematicians bathroom. (Be very grateful that this book is NOT printed in colour.)
All The Shape And Lump Formulas You'll Probably NEVER Need! 791j
This chapter is split into
Polygonalish Formulas - these include odd areas, awkward diagonals, inscribed and circumscribed circles, explanations of SIN COS and TAN, and also some semiperimeter cows. But just when you think it was getting easy - Professor Fiendish comes and chops your door into a septagon. There's also a special guest star appearance by three MM readers who helped with a special trapezium area formula!
Bizarre Boxes - as well as formulas for pyramids and regular solids, you'll find the fastest way for a snail to chase a woodworm round a block!
PI Formulas - as well as circles, ellipses and ellispoids and some head-splitting crescent formulas, there are formulas for doughnuts, ice creams, Pongo's fried eggs, and AT LAST you get to see the tragic tale of The Perfect Sausage. Meanwhile the great Reeve does a superb cartoon strip showing Archimedes's favourite discovery!
When Brett Shuffler knocks down Riverboat Lil's card house, two strangers step in with amazing formulas to make Brett wish he'd stayed at home! This chapter contains lots of wild and weird formulas suggested by our readers ranging from tempertaure conversions to lightning distance. Meanwhile the Evil Gollarks try to find a joke funny enough to destroy the earth!

In the back pages of The Perfect Sausage you'll see a cartoon strip featuring Kjartan Poskitt and the MM editor Lisa Edwards (also known on this website as Lulu Moody). Just so you know, here's what they really look like together!
