## Using Calculation Modes

## Technical Information

**Calculation Mode**

Before starting a calculation, you must first enter the correct mode as indicated in the table below.

**fx-82MS/fx-85MS/fx-300MS/fx-350MS**

When you want to perform this type of operation: |
Perform this key operation: |
---|---|

General calculations | (COMP) |

Regression calculations | (REG) |

**fx-220 PLUS**

When you want to perform this type of operation: |
Perform this key operation: |
---|---|

General calculations | (COMP) |

Standard deviation | (SD) |

**Note**

The initial default calculation mode is the COMP Mode.

Mode indicators appear in the upper part of the display.

The COMP, SD, and REG Modes can be used in combination with the angle unit settings.

Be sure to check the current calculation mode (SD, REG, COMP) and angle unit setting (Deg, Rad, Gra) before beginning a calculation.
