The Arithmetic Kit is a 2-in-1 and consists of two models: a Mechanical Addiator and a Mechanical Multiplier. The Mechanical Addiator is a compact arithmetic machine that works by moving gear racks, using a stylus included in the kit. By moving the sliding racks, marked with arrows and numbers from 0 to 9, you can add and subtract numbers. The Mechanical Multiplier is a flat hinge mechanism that accomplishes binary operations on numbers. By moving the dual slider, you can multiply and square numbers from 1 to 12, making the multiplication table fun. Discover more at worldwide and at in Ukraine.
