There are a lot of What is the solution set that are available online.
Although I do dislike the fact that I would have to pay to get a better expirience and get the plus to have it explain it to me better. And the thing that just made me love this app even more is the care that you do for your users, does everything you need, just take a pic and it gives you the solution.
A must get app for all the people who suck a math like me. Absolutely beautiful app less long nights, because of this app I am able to get the birthday presents I wanted for my birthday in 2 days, best math app, but can't solve certain calculus problem yet, especially great with fractions and exponents.
A great app. A perfect app of the few little. Amazing app, an extremely useful teaching tool or crutch when needed, any problem you need done it will do, it is very simple and easy to use, and I have not yet encountered anything wrong with it.
