Can you explain Fermat''s Last Theorem? What is the shape of the Universe? And how do you add up to infinity? Challenge yourself with Get Smart: Maths and learn to think and talk like the world''s greatest mathematical geniuses. Taking you on a journey through the mathematical ideas that underpin our world - from imaginary numbers and Turing machines to chaos theory and mathematical paradoxes; from the search for primes and game theory to relativity and the arithmetic of altruism - Get Smart: Maths demystifies 50 key concepts and provides you with the tools to master the very biggest ideas. Includes: imaginary numbers; the riemann hypothesis; mathematical paradoxes; chaos theory; code breaking; Gödel''s incompleteness theorem; topology; the Poincaré conjecture; game theory; the maths of symmetry; calculus; Turing machines; fractals; the prisoner''s dilemma; primes; knot theory; probability and statistics; the Monty Hall problem . . . and many more.

Why 60 seconds in a minute? Who invented zero? What exactly is pi? Why do mathematicians hunt prime numbers? And how can you get a number bigger than infinity? To find out, take a tour through 200 important, fascinating and unusual numbers - the easy and entertaining way to grasp mathematics. Numbers in Minutes demystifies the maths surrounding the key numbers including: zero, 1-40, negatives, percentages, prime numbers, fractions, decimals, pi, exponentials, imaginary numbers, squares and cubes, roots and powers, Fibonacci numbers, the golden ratio, millions and trillions, a googol, ''perfect,'' ''kissing,'' ''vampire'' and ''weird'' numbers, infinity, infinity+1 and other sizes of infinity...Every number is explained in a few short paragraphs with a helpful picture, making the maths simple to understand and remember.
