STEM Arithmetic Lab – Dual Mechanical Addiator & Multiplier Educational Kit

An interactive educational STEM kit designed to demystify the foundations of mathematics through the beauty of mechanical engineering. This dual-model set features a Mechanical Addiator and a Mechanical Multiplier, offering a hands-on journey into how physical gears and levers can perform complex calculations without a single drop of electricity.

The Addiator utilizes a precision gear-rack system to perform addition and subtraction, while the Multiplier employs a sophisticated hinge-lever mechanism to multiply and square numbers from 1 to 12. To bridge the gap between classic mechanics and modern learning, the kit includes a QR-code study guide and access to an AR (Augmented Reality) app that visualizes the internal logic of the machines. Suitable for ages 8+, this glue-free assembly is the perfect gateway to computer science and mechanical logic.
