🔢 Basic Arithmetic Calculator

How to Use This Basic Calculator

This calculator is designed for quick and easy arithmetic operations.

1. Enter numbers using the digit buttons (0-9).
2. Press an operator button (÷, ×, -, +) for the desired calculation.
3. Enter the next number.
4. Press the '=' button to see the result.
5. Use 'AC' to clear all inputs and start over.
6. You can also use your keyboard for input: number keys, operators (+, -, *, /), Enter for '=', Escape or 'c' for AC, and Backspace to delete the last digit of the current number.

Button Functions

• AC: All Clear - Resets the calculator entirely.
• +/-: Toggle Sign - Changes the current number between positive and negative.
• %: Percent - Converts the current number to its decimal percentage (divides by 100).
• .: Decimal Point - Adds a decimal point for non-integer numbers.

Order of Operations:

• This is a basic calculator that processes operations sequentially as they are entered. It does not follow the standard mathematical order of operations (PEMDAS/BODMAS) for complex expressions entered all at once. For example, 2 + 3 * 4 will be calculated as (2 + 3) * 4 = 20, not 2 + (3 * 4) = 14.
• For calculations requiring a specific order of operations, perform them step-by-step or use a scientific calculator.
