    This calculator has everything you need. I am just starting college and thought this calculator would be too advanced for basic math classes, but it is great for algebra and all the higher level math classes. This calculator is great and gives you all the functions you need to boost your confidence in math. The solve function alone on this calculator is worth the price. If you buy this calculator you will never need to buy another one.

    A more than adequate graphing calculator for my teenage student. Only downside was that it was more advanced than the one their teacher was used to, so the teacher was not able to provide guidance to my child about how to use specific functions on the calculator to complete assigned tasks in the schoolwork.
