CA 2590713

A tool for teaching numbers and mathematics comprises a 10 by 10 array of cells containing the numbers 00 to 99 in two digit form, increasing in serial order from the lower left of the array, a set of symbols each uniquely associated with one of the prime numbers from 02 to at least 13 and a symbol associated with any other prime number. Each cell containing a non- prime number shows a combination of the symbols associated with the factors of the non- prime number. This aids in teaching addition, subtraction, multiplication, and division. The tool also represents part of the Cartesian coordinate plane which makes it useful for teaching algebra and geometry.
