This model is a Simple LEGO Technic Calculator. It can perform additions, subtractions, and calculate the average of two numbers.
Please note that this model is just a proof-of-concept to realise an idea, and that this idea could be extended to create a more comprehensive calculator. This is not a finished model.
Larger numbers could be calculated if the gear racks were longer or a different scale was used on the labels.
This model was inspired by Alex Allmont's Lego analoge adders (https://youtu.be/OoRmgR5pk9E).
This model is not an official LEGO set.
This model is not for sale.
I do not have building instructions for this model.
