Advanced operations with a clean interface.
What is a Scientific Calculator?
A Scientific Calculator is an advanced mathematical tool that goes beyond basic arithmetic (add, subtract, multiply, divide) to handle complex engineering, scientific, and mathematical functions. It is essential for students, engineers, and scientists working with trigonometry, algebra, calculus, and statistics.
Unlike a standard grocery store calculator, a scientific calculator respects the 'Order of Operations' (PEMDAS/BODMAS). This means if you type `2 + 3 × 4`, it correctly calculates `14` (multiplication first) rather than `20`. This logical precision is critical for solving multi-step equations without intermediate errors.
Our tool includes a full suite of trigonometric functions (Sine, Cosine, Tangent) for geometry, logarithmic functions (log, ln) for growth/decay arithmetic, and exponential functions (powers, roots). It runs entirely in your browser using high-precision JavaScript floating-point math, ensuring instant results without page reloads.
Designed with a clean, physical-calculator-inspired UI, it features a large expression display that shows your entire input history (e.g., `sin(30) + log(100)`), so you can verify exactly what you typed before hitting equals.
1How to Use
- Enter Numbers: Use the on-screen keypad to input numbers.
- Select Operation: Choose basic math (+, -, ×, ÷) or advanced functions.
- Use Functions: For functions like `sin` or `sqrt`, click the button first, then the number. Example: `sqrt(` then `16` then `)`. press `=` to get 4.
- Parentheses: Use `(` and `)` to group parts of your equation. Example: `(2+3)×5` gives 25.
- Powers: Use `xⁿ` (caret `^`) for exponents. `2^3` equals 8.
- Calculate: Press the large `=` button to evaluate the expression.
- Clear: Press `AC` (All Clear) to reset everything, or `⌫` (Backspace) to correct the last character.
