Ugears ‘STEM lab’ collection offers you an amazing opportunity to assemble two pieces of mathematical precision equipment: a Mechanical Addiator and a Mechanical Multiplier and perform basic mathematical operations using the laws of mechanics.
The QR code provided with the model gives you a chance to take a more in-depth look at the mechanism, as well as work with formulas and fun extra assignments.
A special AR application from Ugears gives you a chance to interact with these models at a new level and enhance your understanding of the principles of their operation.
The men responsible for creating the original ‘Addiator’ and ‘Multiplier’ versions were Heinrich Kummer, a music teacher from St. Petersburg, and William Henry Robertson, a math teacher from the U.S.
The Mechanical Addiator is an adding machine, which lets you subtract and add numbers. Use a stylus to move gear racks marked with arrows and numbers from 0 to 9 to perform the simplest math tasks in a fun way!
The Multiplier is a flat hinge device capable of performing binary operations.
Move the dual slider and multiply numbers from 1 to 12 in an effortless and engaging way!
Like all Ugears STEM models, the Addiator and Multiplier are designed to be an educational tool, rather than a merely entertaining puzzle. Their assembly is easy and fast (compared to Ugears more sophisticated models) and the learning benefits are plentiful.
