This is a new book. Condition: Brand New.
Add a little math to your lateral thinking! Paul Sloane and Des MacHale, the crown princes of lateral thinking, have provided a cool twist to test solvers' skills. They present you with mathematical conundrums . . . but instead of requiring brute calculating power, each puzzle relies upon a clever insight or unexpected shortcut. You'll get a brain-busting workout you'll never forget!
