One of the best part is that the answers are the accurate I really love it, warning with Calc, you have to pay attention to the end goal there are too many variables, so if you know what the question is asking it will help you get through each stuff in fraction of the time.
Amazing app and a total life saver. If I habe the same result as the app - great! If not, I can try to find the error myself or just let the app explain it to me, i can tell you right no matter what the rest of the ratings say this app is the BEST! They never get a question wrong and the step by step solution helps alot and all of it for FREE.
