A very basic and simple addition tutor I made for my 5 yo son while travelling around on vacation without internet access. He suddenly became very interested in learning about numbers and adding them up. Also, he refused to use the mouse, because he wanted to "use the computer like a real grown up" (so much for fancy GUI design...) The sums for the problems generated by this project only range from 2 to 10. Press the according numbers keys to enter an answer ("0" for the number 10). Space for the solution. There is absolutely nothing remarkable about this project, except for my sonorous (albeit heavily laptop-mic-distorted and compressed) voice and proof of my ample German vocabulary :)
