Abstract
An aid for teaching mathematical concepts looks like a multiplication table but has separable rows of numbers. In the first row, cardinal numbers 1-n are displayed and second-N rows have cardinal numbers 2-n displayed along side one edge on the face. The remainder of the rows have the multiplication products of the cardinal numbers on the first row and the cardinal numbers of the rest of the rows arranged at the intersections of the cardinal numbers at the top and along side the edge. The rows are separable so they may be arranged in a multiplicity of pairs of fractional equivalents.
