Basic Arithmetic Operations
This calculator is designed for quick and accurate day-to-day computations. It handles the four fundamental operations of arithmetic:
[Image of basic arithmetic operations]- Addition (+): Finding the total or sum by combining two or more numbers.
- Subtraction (-): Finding the difference between two numbers.
- Multiplication (*): Scaling one number by another (repeated addition).
- Division (/): Splitting a number into equal parts or groups.
Order of Operations
Even a simple calculator follows math rules. If you enter 2 + 3 * 4, the calculator will perform multiplication before addition, giving you 14 (not 20).
You can use parentheses ( ) to force a specific order, such as (2 + 3) * 4 to get 20.
