It can solve equations, find roots, calculate derivatives, integrate functions, perform matrix operations, do statistics, and more. It also has a lot of apps that are very useful, such as the probability simulation app that lets me simulate random events and see their outcomes. It also has a long battery life that lasts for months without needing to change them.” – A satisfied student
> “This calculator is okay, but not great. I bought it because I needed a graphing calculator for my AP Calculus exam, but I was disappointed by its screen quality and speed. The screen is very small and low-resolution, which makes it hard to see the graphs clearly. The speed is also very slow, which makes it lag when I enter complex expressions or graph multiple functions. I wish I had bought the color version instead, which has a bigger and better screen and faster processor.” – A disappointed customer
