Everything is good, except sometimes the button for sending whatever you scanned can get in the way, but otherwise good for math, overall, THUMBS UP, amazing calculator app; the best I've ever used, saved me a thousand times over on my math homework.
Some answers are wrong when it comes to fractions in equations. Love it ,but the only thing is that you need to pay a monthly fee if you want a further explanation. Explains every stel of a problem for just a 10 second ad.
This is the best app for my homework and it's a life saver. It comes with a camera and calculator functionality, along with some others, though others math problems can't be solved it is already great enough as it as.
