How to Use a Calculator

Calculators are essential for calculating the result of mathematical problems. They can come in the form of a basic online calculator like the one above, a scientific calculator.

This online calculator is a fully featured tool that mimics the functionality of a traditional handheld calculator. It offers:

• Basic Arithmetic Operations: Use the digit and operator buttons (addition, subtraction, multiplication, division) to perform everyday calculations.
• Memory Functions: The MC, MR, M+, and M– buttons let you store a number in memory, recall it later, or adjust it by adding or subtracting the current display value.
• Advanced Functions: Extra buttons are provided for additional operations:
  • Backspace (←): Removes the last character entered.
  • Clear Entry (CE): Clears the current entry without affecting the stored memory.
  • Plus/Minus (±): Toggles the sign of the number on display.
  • Decimal Point (.) for entering floating-point numbers.
  • Percentage (%): Converts the current value into a percentage.
  • Square Root (√): Calculates the square root.
  • Square (x²): Squares the number.
  • Reciprocal (1/x): Computes the reciprocal of the current value.

How to Use It

1. Entering Numbers: Simply click on the digit buttons (0–9) to enter your number.
2. Performing Operations: Click on the appropriate operator button (such as +, −, ×, ÷) to add operations to your calculation.
3. Advanced Features:
   • Memory: Use M+ to add the current number to memory, M– to subtract it, MR to recall the stored value, and MC to clear memory.
   • Editing: If you make a mistake, press the backspace (←) to remove the last digit, or clear the entire display using CE or C.
   • Additional Operations: Use the extra function buttons to calculate percentages, square roots, squares, or reciprocals of the number currently shown.
4. Calculating: When your expression is complete, click the equals (=) button to compute the result, which will be shown on the display.
5. Error Handling: If an invalid operation is entered (like division by zero), the calculator will display an "Error" message.

This calculator is designed with a simple, intuitive interface and clear visual feedback, making it easy for anyone to perform both simple and more advanced calculations directly in their browser.
