Using Memories

The calculator uses global variable memories (A–Z and θ), local variable memories (maximum of nine variables per equation), and a last answer memory used when solving equations.

Using alphabetic characters

You can enter an alphabetic character (written in blue) when ALPHA is displayed at the top of the display. To enter this mode, press ;.

To enter more than one alphabetic character, press @ a to apply the alphabet-lock mode. Press ; to escape from this mode.

NORMAL MODE 0.

Using global variables

You can assign values (numbers) to global variables by pressing x then A–Z and θ.

Example 1

Store 6 in global variable A.

1.Press j 6 x A.

•There is no need to press ; because ALPHA is selected automatically when you press x.
