The Phantom X

by Kjartan Poskitt

Is maths making you miserable? Are you alarmed by algebra and flummoxed by formulas? Do equations make you quake? Look no The Phantom is here to banish algebraic agony for good. Find out what Grizelda the Grisly buys on a shopping trip to the Slaughter-o-Mart, face another diabolical challenge from Professor Fiendish, and enter the Murderous Maths testing laboratory in the disturbing disguise of a Pure Mathematician. Meanwhile, the gangsters discover that, sometimes, x = a big, fat nothing.

This is about functions and figuring out numbers you don't know.

I liked this book because I like maths and that there are problems that you can do in this book.

I don't know who thought of how to put in letters instead of numbers.

Feeling like a teenager again reading this book. Mathematics is a good useful subject I had never be able to put my fingers on why I’m never good at it. May be this is the way I should have been introduced to variations, unknowns, and equations.

an introduction to Algebra - it covers a lot - from the concept of equations to methods to solve... includes linear equations as well as quadratic... presents basic identities, shows graphical representations, describes the Pascal triangle and even touches the binomial theorem... but the best part is its application - illustrated thru stories (magic, games, real life situations) and that actually brings it to life...

the book is for middle grade students - i doubt that a student at that level will grasp everything - but it will serve the purpose if it intrigues them and inspires them to explore further... and opens their mind to mathematical thinking...

I have always wanted to read a Murderous Maths book as it’s always been a favourite with my nephew - but never managed to - till now... and wish that I had a chance reading such books growing up...

The Phantom X has a special character: X. I played lots of math games as I read this book and even convinced mom to play with me. Unfortunately, she didn't agree. The game I convinced her to play was a calculation system with X. Finally I showed her the bottom of page 65 and she didn't even seem surprised.

I actually bought this book from a book where when I didn't understand Algebra. It explains the basics very interestingly and its also humorous!! Liked it very much!
