How tall will my child grow to be? How much does the moon weigh? Is it the heat or the humidity? A unique and engaing collection of everyday imponderables, Go Figure! Provides simple mathematical stepping stones to help you answer these and other "unanswerable" questions. Inside you'll discover solutions to long-standing curiosities on subjects as small as a cricket and as large as the solar system -- from pyramid schemes to the pattern of nines to special math that only works at the ballpark. You'll catch the author's infectious enthusiasm for all things mathematical, and you'll soon realize what mathematicians discovered centuries ago -- math is all around us, providing an underlying logic and symmetry to a world that often appears chaotic to the untrained eye.
