Basic Calculators
Basic calculators are the simplest and most commonly used in schools. They typically require very few key presses to power off.
Steps to Turn Off a Basic Calculator

- Press and hold the ‘OFF’ button until the display goes blank.
- Your calculator should now be turned off. If it’s not, ensure you’re pressing the correct button.
Scientific Calculators
Scientific calculators are more advanced and often require a combination of key presses to turn off. These are commonly used for more complex math problems and need a specific shut-down command.
Steps to Turn Off a Scientific Calculator
- Locate the ‘2nd’ function button. This button typically activates secondary functions of other keys.
- Press the ‘2nd’ button followed by the ‘ON/OFF’ button.
- The display should go blank, indicating the calculator is turned off.
Graphing Calculators
Graphing calculators are the most sophisticated and are typically used in higher-level math classes. Turning off these calculators usually involves multiple steps due to their complex functionalities.
Steps to Turn off a Graphing Calculator
- Find the ‘2nd’ function button, generally on the upper left side of the keypad.
- Press the ‘2nd’ button. This will activate the secondary functionalities of the keys.
