This is a great free app! Has all the functions I was looking for, plus you can type the whole expression before calculating. Update After 3 years, still an amazing calculator, and updates come regularly to address issues.

Great, so far: I still haven't tested this enough so that I could keep this app. So for now it's good, but still a 4star. :)

Works well... It took a bit to figure out some things, incl simple things like 'E' is 'equals' instead of using the '='. I realize it should be obvious (being blessed w ADHD, obvious is only an abstract concept... ;D ) but when the 'help' uses the '=' symbol I kind of expect at least some uniformity. Other than that, it works great. The concern mentioned in 2011 about not being able to solve 1 equation but could the other has been resolved, as I checked it myself. Galaxy Note 2

Cannot solve expressions when a constant multiplies a variable, like 82x²=0 (it will solve 4x²=0 though). Will change my rating if this is fixed.

Approved Really good features for plotting and statistics, given that it's free. Could use more functions, though, like calculus, complex numbers, bit operatio

Doesn't remember degree/Radian choice when restarting phone. Animation when answer appears is annoying  would be better to have a two line display.

Can a formula be entered with various unknowns and then solve for the unkown? Will the solver rearrange the equation automatically?
