If a bowling club can only get a lane on the fifth Saturday of every month, how many times in a year will it meet? Can you figure out the next number in this row of seemingly unconnected figures (1, 8, 11, 69, 88, 96, 101.)? How many cuts would it take to saw a chessboard into 64 separate pieces? You don't have to be a mathematician to get hooked on these stimulating braintwistersto find the solutions, all you need is a good dose of logic or the simplest school arithmetic. To add a little more pleasure to the puzzles, every reallife problem unfolds in small, interesting stories about friends and families as they go about their daily activities. And, they're all wittily illustrated, too! From calculating the price of lollipops to working out the size of a pond in a village park, this is pure number fun!
