A Mechanical Calculator in LEGO

Hi, here are 3 linkages you can use to actually calculate things. It's probably not accurate enough to use it in real life, but it's definitely a neat mechanical principle. Enjoy watching, 2in1 -------------------------------------------------------------- I don't really know who to give credit to since I don't really know who invented the mechanisms originally, but ‪@thang010146‬ was a really helpful resource for the project. The Lego builds are my own design, of course.
