Math Games for Middle School pdf epub mobi txt 電子書 下載 2024
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.
