The Murderous Maths Books

Scientific American recommendation! Jan 2011

"Have a look at Murderous Maths by Kjartan Poskitt. It is a truly addictive reading book, and was leapt on and devoured by my children. The book is full of awful jokes, fascinating facts, real murders and yes, the maths is good too.
This is a brilliant book."
- New Scientist 22nd November 1997 -

How did "Murderous Maths" start?

This is the artist
who painted all the covers. Originally the first two Murderous Maths books were in Scholastic's "The Knowledge" series (this followed on from the Horrible Histories and Horrible Science books) but now they headline their own "Murderous Maths" series. What makes them different from other maths books is that they are FUNNY.

All the Murderous Maths books feature a range of characters including One-Finger Jimmy, Half Smile and their gang, Dolly Snowlips, Professor Fiendish, Pongo McWhiffy and the terribly lovely Veronica Gumfloss, the evil Gollarks from the planet Zog, Urgum the Axeman and so on. They also include sneaky tricks, games, jokes (most of which are repeatable) and what's more - you'll find yourself picking up all sorts of advice and tips on how to cope with maths in all its various forms. Despite their irreverent and frivolous attitude, these books have even found their way into schools and proved to be a boost to GCSE studies. The books are also available in foreign editions which already include German, Spanish, Polish, Greek, Dutch, Norwegian, Turkish, Croatian, Italian, Lithuanian, Korean, Danish, Chinese, Portugese, French, Hungarian, Swedish, Finnish, Thai, Portuguese (Latin America)... and a few we can't identify!

So who invented Murderous Maths then?

The books are all written by Kjartan Poskitt and the bulk of the artwork is done by Philip Reeve. Click here to find out more about the author and illustrators!

Over the years we've been delighted to have so many families, students and homeschoolers visiting us from across the Atlantic that we've set up a special USA visitor page.

Here's the USA and CANADA version of the MM Sudoku book which has sold well over 1/2 a million copies!
In the meantime we are waiting to hear if/when American editions will be published, so if you're one of the many visitors we've had from Virginia, New York, Massachusetts, California, Ohio or elsewhere in the US, do please ask at your local bookstore, or even better contact:

Scholastic Inc. 555 Broadway, New York, NY 10012.

That way you might get a book called "Murderous Math" rather than "Murderous Maths"!

We would also love to hear from you!
