This repo is directly tied to it's Rails backend which can be found at: https://github.com/matthewstclaire/flashcard-project-backend. Follow the guide on that repo to clone and run a server. Without this the Chalkboard Math App will not display any questions or have the ability to save questions made.
This app allows you to add basic math questions as you see fit. They are then stored in the backend which is a Rails API that I have made. You will also be able to delete questions as you see fit.
