ISingle-character Variable Precautions

Your ClassPad supports the use of single-character variables, which are variables whose names consist of a single character like “a” or “x”. Some ClassPad keys (7, 8, ' keypad keys, math (mth) soft keyboard 7, 8, 9, :keys, 5key set keys, etc.) are dedicated single-character variable name input keys. You cannot use such a key to input a variable name that has more than one character.

For example, pressing the keypad keys 7and 8in succession is interpreted by the ClassPad as the multiplication expression “x σ y”, and not as the characters “xy”. In order to input a variable name made up of two or more characters, use the alphabet (abc) keyboard. For more information, see “Using Single-character Variables” on page 1-6-12.

ICreating a New Variable

The most common way to create a new variable is assigning a value or expression to the applicable variable name. Use the variable assignment key (6) to assign data to a variable.

Assign key

This key is included on the math (mth) and 2D soft keyboards.

The following is an example of assignment to a variable while “main” is specified as the current folder.

Example: To create a new variable named “eq1” and assign the expression 2x + 1 to it The following assumes that there are no variables named “eq1” or “x” currently in the “main” folder.
