Awsome
I love the app, just wanted to let you know that there is an error on the summary on lesson 3, in the addition part.
Thanks
Thanks

Quick to learn
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.
valosmiff,
Very good practice
I’m an adult trying to teach my kids how to use an abacus, even though I never learned. This app is great practice. The explanations are better than YouTube.
Jason7x7,
Great learning tool
Just needs a good English editor.
