# Practice Problems

## About

This practice problems tool contains a bank of problems here to help test your knowledge and solidify learned concepts. When a topic is selected, problems will be randomly selected from the problem bank. After the correct answers is given or the "Give Up" button is pressed, you will have the option to rate the problem's difficulty and move on to another problem. Problems range in difficulty from "Very Easy" to "Very Hard," which is displayed as a colored square in the upper right corner.

* For scientific notation, use E*x* to represent 10^{x} (e.g. 1.7x10^{5} would be input as 1.7E5).

* For exponents, use *x*^(*n*) to represent *x*^{n} (e.g. e^{(1+2i)x} would be input as e^((1+2i)x).
