UGEARS STEM LAB ARITHMETIC KIT

INSTRUCTIONS:  Pdf: Click Here 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 task
