Clearing the Contents of a Specific Variable

Press (STO) and then press the key for the name of the variable whose contents you want to clear. For example, to clear the contents of variable A, press 

(STO) (A).

Clearing the Contents of All Memories

Use the following procedure to clear the contents of Answer Memory, independent memory, and all of the variables.

Press (CLR) (Memory) (Yes).

To cancel the clear operation without doing anything, press

(Cancel) instead of .

Function Calculations

This section explains how to use the calculator’s built- in functions.

Note: The functions available to you depends on the calculation mode you are in. The explanations in this section are mainly about the functions that are available in calculation modes. All of the examples in this section show operation in the COMP Mode ().

Certain function calculations may take some time to display calculation results. Before performing an operation, be sure to wait until execution of the current operation is complete. You can interrupt an ongoing operation by pressing .

Pi (π) and Natural Logarithm Base

You can input pi (π) or natural logarithm base e into a calculation.
