Types of Calculators
Before diving into the methods for turning off calculators, it’s important to understand the different types of calculators available on the market. Each type may have a slightly different method for powering down. Below are the most common types:
1. Basic Calculators
These are simple calculators used for basic arithmetic operations such as addition, subtraction, multiplication, and division.
2. Scientific Calculators
Scientific calculators are used for more complex calculations, including trigonometric functions, logarithms, and statistical calculations.
3. Graphing Calculators
These advanced calculators can plot graphs and solve equations. They are commonly used in higher-level mathematics and engineering courses.
4. Smartphone Calculators
Most smartphones come with a built-in calculator app that functions like a basic or scientific calculator.
How to Turn Off Different Types of Calculators
Now that you know the different types of calculators, let’s look at how to turn them off.
Basic Calculators
Turning off a basic calculator is usually straightforward. Here’s how:
- Method 1: Power Button
- Locate the power button, usually marked with a “ON/OFF” label.
- Press the power button once to turn off the device.

- Many basic calculators have an automatic shut-off feature. If left idle for a certain period (usually around 5-10 minutes), they will turn off on their own.
- Method 1: Power Button
- Similar to basic calculators, look for the power button (often labeled as “ON/OFF”).
- Press it once to turn off the calculator.
- Method 2: Shift Key
- Some scientific calculators require you to press the “SHIFT” key followed by the “ON” key to turn off the device.
- Method 3: Automatic Shut-off
- Like basic calculators, many scientific models feature an automatic shut-off function. If not used for a specified time, they will turn off automatically.
- Method 1: Power Button
- Locate the power button, which is usually labeled “ON” or “OFF.”
- Press it to turn off the calculator.
- Method 2: Menu Navigation
- Some graphing calculators have a menu option for shutting down. Navigate to the “Mode” or “Settings” menu and look for a “Turn Off” option.
- Method 3: Automatic Shut-off
- Most graphing calculators also have an automatic shut-off feature that activates after a period of inactivity.
- Method 1: Close the App
- On iOS: Swipe up from the bottom of the screen (or double-click the home button) to access the app switcher. Swipe the calculator app off the screen.
- On Android: Tap the square icon (recent apps) and swipe the calculator app off the screen.
- Method 2: Lock the Phone
- Simply lock your phone, and the calculator app will close automatically.
- Regularly Change Batteries
- If your calculator uses batteries, replace them periodically to avoid sudden shutdowns.
- Keep it Clean
- Wipe the calculator’s surface with a soft cloth to remove dirt and grime.
- Store Properly
- When not in use, store your calculator in a protective case to prevent damage.
- Avoid Exposure to Extreme Temperatures
- Keep the calculator away from direct sunlight, heat, or moisture to prevent internal damage.
Scientific Calculators
Turning off a scientific calculator may involve slightly different steps:
Graphing Calculators
Graphing calculators can be more complex, but turning them off is still a simple process:
Smartphone Calculators
When using a smartphone calculator, turning it off is often synonymous with closing the app:
