Unofficial simple web app for practicing the tricks and tips taught in Edward H. Julius' book "Rapid Math Tricks And Tips". You can build it yourself from source or you can try it out here: https://djmclaugh.com/RapidMathTricksAndTipsPractice/
npm install (only need to run once after you clone the repository)
npm run-script build (run after npm install and every time you want your changes to take effect)
This will generate the bundle.js file in the app directory.
Once the app/bundle.js is generated, simply open app/index.html with your favorite browser.
