When there is more than one definition for the same symbol, the calculator
uses the first definition. To avoid confusion, do not define a symbol more
than once. If you want to change the value of a symbol, use the arrow keys to
go back to the original definition and change it.
• When you are prompted for the value of a symbol, you can enter another
expression rather than a simple number. Type:
5
When prompted for the value of b, enter:
The Calculator displays the value of b at the bottom of the screen and fills in
the result of b + 3 on the line above.
