What a deal for not just one but TWO multifunctional calculators!
Wow! What a great deal! I bought these for my high school daughter because I had already gotten the heads up that the expensive TI-83s and TI84s often walk off (aka get stolen), so I read many reviews and looked at all the calculator functions and found these calculators to be an exceptionally good price and well equipped to help her in honors geometry all the way through calculus. I have gone through complex statistics and multi variable calculus and found these calculators to have all the functions needed to help her through high school and college. The graphing function may not be as high tech but often excel is a better options for such needs especially in today’s tech driven world. The bonus is that I won’t have to run out in desperation if she loses one because it comes with a back up and also it is great that she can keep one at hime and one in her backpack for school so she will be accustomed to the use of one calculator instead of switching between brands. The other great part is one calculator did not work and amazon quickly sent another double pack within two days. Amazon you rock! Hope this helps some other parents debating on whether the less expensive calculator is just as good and I say yes. Also this calculator is allowed for all standardized testing.

I'm still not sure to operate it correctly.
I took Calculus I as an elective course. I haven't fully mastered the operation of the calculator yet because I have many limit problems, but I can't find the symbols for the limits.

Check with teacher first
This said it could do everything needed. Kids teacher looked at it and it was missing some important functions.
