Arithmetic Trinomial Cube

$80.00

Arithmetic Trinomial Cube is backordered and will ship as soon as it is back in stock.

This cube represents the equation (a+b+c)³ in concrete form and differs from the Trinomial Cube in that the component pieces are colour-coded to represent hierarchical values from one unit to one million.  This makes it possible for the child to equate an arithmetical value to each of the cubes and prisms.  Contained in a hinged wooden box with lid.
