Entering Expressions and Instructions

What Is an Expression?

An expression is a group of numbers, variables, functions and their arguments, or a combination of

these elements. An expression evaluates to a single answer. On the TI-84 Plus, you enter an

expression in the same order as you would write it on paper. For example, pR

is an expression.

You can use an expression on the home screen to calculate an answer. In most places where a

value is required, you can use an expression to enter a value.
