It also explains how they get the answer asvwell, it solves everything I put in, efficiently, quickly, and hassle free, i absolutely LOVE this, this app is alright, I like using it to figure the questions I cannot figure out but some of the time for the hard questions it wants you to pay and as a student I have both A no job and B only so much money, all in all a great app, the developers defiantly deserve to make you pay for more features.
