Math on Call: A Mathematics Handbook
Absolutely Fantastic, December 6, 1999
This has to be one of the best mathematical reference books published today. It covers a wide range of topics from number theory, algebra, geometry, fractions, probability, statistics, ratios, etc. in a simple, highly illustrated, and easily referenced index to almost any math problem encountered by elementary to high school. Highly recommend you keep a copy at home for children’;s homework help and one at the office for reference. It’s that good. Wish Amazon would place a few illustrations from the book on-line to enable prospective buyers a chnace yo see how well the authors present this material. Should be on anyone with children’s MUST HAVE list.
