Description

Volunteering for an unofficial math education startup, I collaborated with the project lead to ensure that my first program aligned with the startup's goals and vision of finding unique, creative ways to teach math.

The end result is an interactive program that visually explains how the process of long multiplication works, by having the user tap a virtual graham cracker to split it into the individual components that are summed in a long multiplication problem, showing how the method breaks down the problem into easier steps.

This program was built using a Javascript library I created for P5JS (Mobile Friendly Cursor library).
