This project is an interactive addition tutorial. A dog, Professor Barkinsums, shows you how to add two non negative integers between 0 and 999.
Then you can give it a try.
You can draw with the chalk and erase with the eraser. Try clicking on the dog. Hover over the switch and it will tell you what it does.
