Entering an Expression

Enter the numerical expression on the entry line. The expression
can consist of positive and/or negative whole numbers that are
added or subtracted. Therefore, you can use the following keys:
all number keys, \, T and a. Enter the values as you would on
the Home screen of the TI-73.
You can add a positive value in two ways:
• Use \ to add a positive number. Example:
• Use T a to subtract a negative number.
