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.
High-quality ecological plywood pieces and a step-by-step color manual make the process a seamless and enjoyable one! Everything you need is in one box, without the need to use glue or extra tools.

Use the Addiator to add and subtract numbers. Use a stylus to enter a number value, then enter a second number. The result of the desired mathematical operation is then shown. The top row of entering the second number is for addition, while the bottom row is for subtraction. In addition to this, the Addiator can be used to multiply and divide numbers.The multiplication tables from 1 to 12 will never again be deemed as ‘boring’ with the Ugears Mechanical Multiplier! The principle of hinge-lever mechanisms is perfectly exemplified with this wonder of a tool. Simply move two sliders to various numbers and see the result in the window above. If you want to square a number (to multiply a number by itself), the move the right slider to the utmost right position and fix it at the “X²” symbol.
