This is a simplified Calculator (from my 2018 design) that can handle addition and subtraction, and negative number answers. I am currently working on further simplifying and adding multiplication and division to the Calculator.

This design makes use of a decimal serial subtractor as it's core, allowing everything to be may more compact than a conventional Minecraft calculator. Inputs can be up to 4 digits long.





A negative number answer will take a while and look glitchy for a few seconds but it does work! Listen for a note block to signify the answer being un-scrambled



this project is still a work in progress.
Please let me know anything else you'd like to see :)
