I learned basic addition and subtraction quickly. I’m just on lesson four, but the simple explanations are very helpful. Five stars if I were able to use if in landscape view.

I honestly think this is such a great app. I’ve always wanted to be quick in arithmetic and one day I saw a video of kids being able to add/subtract large number within seconds and immediately knew that I wanted to learn this method. When I stumbled across this app I thought it was the perfect opportunity and I’m really enjoy it so far. Thank you to the creator of this app!!!!
