Invicta Sum Setter.

A novel, self-contained device which offers virtually unlimited variations of four mathematical operations.

A roll of the big clear die makes the two 10-sided dice land in a random sequence. The symbol uppermost on the die acts as the mathematical operation.

Removeable symbols (+- x÷) allow teachers to match the level of ability of their pupils.

Complete with product guide. 70mm x 70mm.
