IUsing Single-character Variables

As its name suggests, a single-character variable is a variable name that consists of a single character like “a” or “x”. Input of single-character variable names is subject to different rules than input of a series of multiple characters (like “abc”).

STo input a single-character variable name

Any character you input using any one of the following techniques is always treated as a single-character variable.

•Tapping any key in the math (mth) keyboard’s 5key set (page 1-6-10)•Tapping any key in the 2D keyboard’s 5key set (page 1-6-17)

•Tapping the 7, 8, 9or :key to the left of the  key of the math (mth) keyboard or 2D keyboard

•Pressing the 7, 8, or 'keypad key

If you use the above key operations to input a series of characters, each one is treated as a

single-character variable. Inputting , !, ", for example, is treated as the mathematical expression a σ b σ c, and not as the characters “abc”.

Tip

•The single-character variables described above make it possible for you to perform calculations as they appear in your textbook.

Example 1: 5 !"UExample 2: 78

Tip

•When you input a single-character variable, its name appears on the display as an italicized bold character. This is simply to let you know that the letter is a single-character variable name.
