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 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.

#WHY WE LOVE UGEARS?
We love Ugears for its beauty and challenge. Each of the models is a mechanical masterpiece that you get to put together yourself. For anyone who loves to make models, design or just tinker, this will make you want to do more. Patience and perseverance are required skills, not so much age. Although I would recommend that kids under 13 years that be helped out by an adult. Now just up to you to choose your model. Good Luck!
