What Is a Basic Calculator?

A basic calculator is a tool designed for performing fundamental arithmetic operations such as addition, subtraction, multiplication, and division. It also supports additional functions like calculating percentages, squares, and square roots, making it ideal for everyday calculations.

How to Use a Basic Calculator

Follow these steps to use the calculator effectively:

• Enter Numbers and Operations: Use the number and operator buttons to build your expression (e.g., 5 + 3).
• Use Additional Functions: Click buttons like x² for squares or √ for square roots.
• Parentheses: Use ( and ) to control the order of operations.
• Evaluate: Press = to see the result, which will also be logged in the history.
• Clear: Use the C button to reset the calculator.

Common Functions

Here are some commonly used functions:

• Arithmetic Operations: Addition (+), Subtraction (-), Multiplication (×), Division (/).
• Percentage (%): Calculate percentages easily (e.g., 20% of 50).
• Square (x²): Compute the square of a number.
• Square Root (√): Find the square root of a number.
• Parentheses: Group expressions for correct order of operations.

Tips for Accurate Calculations

Ensure precision with these tips:

• Use Parentheses: Group expressions correctly (e.g., (5 + 3) * 2 instead of 5 + 3 * 2).
• Clear Regularly: Use the C button to reset the calculator before a new calculation.
• Review History: Check the calculation history to spot errors.
• Double-Check Inputs: Ensure you’ve entered the correct numbers and operations.
