In this chapter, you will learn the basic ideas that will be the foundation for using all the features of Sage. We will start by learning how to use the command line and notebook interfaces efficiently. Then, we'll look at basic concepts like variables, operators, functions, and objects. By the end of the chapter, you should be able to use Sage like a sophisticated scientific graphing calculator.
