Ya the calculator still works perfectly.
I wanted to put the batteries on the inside initially however its impossible to have AAs and the mp3 player in there without adding like half an inch to the case thickness.
I could fit a Li-ion in there, but I would have to find some cash to do that. I would have to build a charging circuit for it as well, and the Li-ion probably won't last as long as AAs would.

It would be nice though. I should probably start looking for a battery that would work.

Having the mp3 controls on the back is 1337 because I can hold the calculator like normal and calculate and change songs/volume or whatever at the same time.

So I think I'll leave the controls back there.
Thanks for the suggestions guys!!
