Capable, but with a steep learning curve
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.There is a lot of functionality in this calculstor, especially for individuals going through an alectrical engineering degree. But it doesn’t function like a standard calculator in a few ways. Once you get used to it, it’s ok, but can still be annoying when you just need a calculator. I still keepvanother calculator on hand for most of my math (TI 36X Pro) includijg imaginary numbers and polar values.

Does what is needed for my student
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.With a new high-schooler needing a certain calculator, we decided to buy something that she can use in later grades. This calculator does the trick. And, is easy to use.

Nice calculator.
||Posted . Owned for 1.5 years when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.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.

Great Calculator For Calculus and advanced Math
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.Had this calculator and used for Calculus 1,2,&3. I had a tab break on the battery connector and had to replace after three years and purchased same model. Very happy with it and after I figured out the layout of the menus, it was very user friendly. It has more functions than I will probably ever use but will handle everything I need it to do.

Meets expectations
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.Gave this to my son for his SAT test and pre-cal. It works for him. We initially gave him a more advanced version but did not suit his needs as a junior student. It looks nice and well-built. I hope it lasts and he can use it till college. Very satisfied with this purchase.
