UGears STEM Lab Arithmetic Kit

Assemble the Arithmetic Kit and discover how the Mechanical Addiator and Mechanical Multiplier work. The model kit comes with a QR-code to the study guide about the mechanisms, the principal of their working, the main characteristics, and formulas. It also includes interesting assignments. Dive into augmented reality and look at how Mechanical Addiator and Mechanical Multiplier work. Interact with the models via a special AR application from Ugears. UGEARS' Arithmetic Model Kit, part of UGEARS' STEM Lab collection, consists of two ready-to-assemble models: A Mechanical Addiator and a Mechanical Multiplier. + Read More Find out how the Mechanical Addiator and Mechanical Multiplier work The Mechanical Addiator is a compact arithmetic machine (or adding 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
