Editorial Reviews

Viewed upside down, most of the numbers on a calculator's display look like letters. For years, children have been spelling words with hand-held calculators, but Adler takes the game a step further. He poses a series of riddles, each accompanied by an arithmetic problem involving some combination of addition, subtraction, multiplication, and division. Solve the math problem with a calculator, turn the calculator upside down, and you have the answer to the riddle. Ink drawings with gray washes set a humorous tone, but these aren't the funniest riddles around. Still, children playing around with calculators may find the book's novelty reason enough to pursue the answers.
