## 4.1 Entering Math Expressions

There are two ways to enter symbolic or numeric math expressions as part of your responses to questions.

- The system default mode is
**Text Mode**, in which you enter symbolic or numeric math expressions in a simple keyboard notation, much like a graphing calculator.

- You can also use the
**Symbol Mode**, which allows you to enter formulas in the **Equation Editor**, pick algebraic symbols and operators from a palette, and see your expressions appear in standard mathematical layout as you type.
