User reviews

it would be cool if the equations get harder after a while. After 3 weeks of using it a 1x1 equation is quite easy to solve. And there is this weird space between the math sign and the second number. I would have loved to pull this from github, but i didnt found it.

Great idea, however it'd be neat to have some form of validation so that you could verify your math, i.e. if you saw 8*8 and typed "64" then the math would fade away and a green checkmark (or something similiar) would fade in instead.
