How to Reset a Calculator
Resetting your calculator to default settings involves clearing all stored data and restoring factory settings. The process varies depending on the calculator type and brand.
Step-by-Step Guide
- Locate the reset button on your calculator. This is typically a small button labeled "Reset," "AC," or "ON/C."
- Press and hold the reset button for 3-5 seconds until the calculator beeps or displays a reset confirmation message.
- Wait for the calculator to restart. Some calculators may display a factory reset message.

Note: Resetting your calculator will erase all stored data, including memory values and custom settings. Make sure to save any important information before proceeding.
