Tell it what it needs to solve for, for example you can tell it to solve for X and it will. I am very amazed to see that it is capable to solve every part od maths either it's algebra, statistics, calculus or whateversoever, it can solve everything. Now I don't need to ask my teacher or parents to solve my math problems.
I hope you will develop even more apps like this to spread the beauty of education for free. But you do have to remember, it can't to everything for you, this the best app ever and this help my son so much.
I for sure know my homework now. Just make sure to have a very neat handwriting without cursive writing. Anyways this is a great app to use when you want to check your answer (or even cheat), this app is great, it really solves your problems in mathematics, shows the steps, and doesn't have many adds.
