# WarpPI Calculator
Step-by-step algebra calculator for Raspberry PI.

**This project is experimental and strictly related to my calculator, designed to run on a raspberry PI Zero.**<br>
**Many fundamental features are missing, this project is still in its infancy.**<br>

**If you really want to build and test it on your computer take account of that.**

This preview has been built using TeaVM: a JVM made in javascript.
Obviously it runs slower than the original.
