• The examples on the transparency masters
assume all default settings.
•To use G, enter the base, press G, and then

• In Classic mode, exponentiation using the G
key is evaluated from left to right. The

with the result of 64.
In MathPrint™ mode, exponentiation using
the G key is evaluated from right to left.
Pressing 2 G 3 G 2 displays as , with
the result of 512.
