Mathemagic

Mathemagic by Blum, Raymond. paperback edition. ISBN: 9780806983554.

"Youngsters are fascinated by magic, and the idea of making it happen in front of friends and family is appealing. These math "magic" exercises begin with the simple and progress to the complex, letting readers find their own levels. Many use a calculator, some require a deck of cards, others just need paper and pencil. There is plenty of material here to amuse and challenge....The directions are clear, and the problems work, so there is a guaranteed audience."--Booklist. 128 pages, 120 b/w illus., 5 3/8 x 8 1/4.
