I have had this calculator for well over 10 years, through high school, college, and my career. I use it daily now as an engineer.  I highly advise against spending money on graphing calculators and anything more than $10.  The reality is, while you're a student, you need to show your work to get full credit, so it's best to learn to do it by hand. This calculator can do every function required for all levels of algebra, trig, calculus (limited functionality, but you'll use computers for anything advanced anyways) and statistics. In fact, I have officially used every single command on the calculator, and have never had to wish my calculator could do more.
