‘ and y 5
‘ key
The ‘ key erases the home screen. This key is located just
below the four blue arrow keys at the upper right corner of the
TI-82 STATS keyboard. If you press ‘ during an entry, it clears
the entry line. If you press ‘ when the cursor is on a blank
line, it clears everything on the home screen.
Although it does not affect the calculation, it is frequently
helpful to clear the previous work from the home screen before
you begin a new problem. As you work through this guide, we
recommend that you press ‘ each time you begin a new
Example. This removes the previous example from the home
screen and ensures that the screen you see matches the one
shown in the example.
y 5
If you accidentally press a menu key, pressing ‘ will
sometimes return you to the home screen, but in most cases you
must press y 5 to leave the menu and return to the home
screen.
