I love the concept of this. I got past the first two levels (after reading the helpful comments below), but my patience gave out at that point. It definitely needs clearer instructions and a simpler introduction. The UI is also a bit awkward. But I could imagine it being a fun progression, maybe if the numbers were reduced in value so that you could quickly do them in your head (though the fact that you use an irl computer to get the answers is pretty funny). Nice work.
