Online Calculator – Simple & Scientific Calculator
This online calculator is a fast, accurate, and easy-to-use tool designed for both basic and advanced mathematical calculations. It works directly in your browser without installation and is optimized for both desktop and mobile devices.
The calculator includes two powerful modes: Basic Calculator and Scientific Calculator, making it suitable for everyday use, education, finance, and engineering tasks.
Simple Calculator (Basic Mode)
The simple calculator mode is designed for quick everyday calculations.
It supports:
- Addition, subtraction, multiplication, and division
- Percentage calculations (%, discounts, increases)
- Decimal numbers and brackets
- Real-time expression input
- Instant result preview
This mode is ideal for:
- Shopping calculations
- Budgeting and finance

- Everyday use
Example calculations:
100 + 20% = 120
50 * 10% = 5
200 – 15% = 170
Scientific Calculator Mode
The scientific calculator mode is designed for advanced mathematical operations and technical use.
It includes all basic functions plus:
- Advanced functions:
- Trigonometric functions: sin, cos, tan
- Logarithmic functions: log, ln
- Powers and exponentiation (^)
