Title: Good for the price
Review: I have only used the TI-83 before purchasing the TI-86.From the few weeks that I have used this calculator, it has saved me a lot of time and effort. The biggest time saving thing on it is the solver and the simultaneous equation solver. What would take me tons of time and an entire page of writing, solving for 3 or even 4 unknowns, now just takes a few seconds. All I have to do is put it in and hit solve!Also, the vector function of this calculator is nice for my Calc III, statics, and Physics classes. It comes most handy when working in 3D. However, the interface is hard to work with and can take too much time. They should come up with a faster and easier to use menu to edit, enter, and use vectors.Other than these things, it does everything the TI-83 does without any trouble. It is a good scientific calculator, as long as your teacher allows it to be used!I am glad I made this purchase.
