From addition and subtraction to plane and space geometry, graphing, simultaneous linear equations, and probability, this book explains middle-school math with problems that kids want to solve: Seventy-five employees of a company buy a lotto ticket together and win $22.5 million. How much does each employee get? Intriguing facts about the history of math show what a human creation it is: Both the Maya and the Hindus of India invented the concept of zero, but the Maya did it first by 400 years; in 1858 Mr. William Shanks, a British mathematician, hand-calculated pi to 707 decimal digits and had them inscribed on his tombstone! Alas, the last 200 or so were wrong.
