    This quick start guide covers basic tasks, such as entering and editing expressions, plotting their graphs, and creating tables of values generated by expressions. It also serves as an introduction to HP apps. HP apps are special applications designed for the study and exploration of a branch of mathematics or to solve problems of one or more special types.
