key set

key displays keys for inputting single-character variables, and changes the
5
softkey to
(
. You can tap this key to toggle between
5
and the initial 2D keyboard.
Tapping the
$

variables.
Tip
• As its name suggests, a single-character variable is a variable name that consists of a single
character like “
a
” or “
x
”. Each character you input on the
5
keyboard is treated as a single-
character variable. You cannot use the
5
keyboard to input multiple-character variable names
like “ab” or multiple-character strings. You must use the alphabet (abc) keyboard when you want
to input a multiple-character string. For more information, see “Using Single-character Variables”
on page 1-6-12.
• For information about the
#
key that appears in the lower right of all of the 2D keyboard key
sets, see “Using the Answer Variable (ans)” on page 2-2-2.
• Note that natural input is available in most applications of the ClassPad. Natural input cannot be
used in the geometry measurement box or when entering data into a list.
