What Is the Scientific Calculator?
This Scientific Calculator evaluates full expressions with order of operations, parentheses, powers and roots, trigonometric functions (with degrees/radians), logarithms, factorials and the constants π and e. Type an expression or tap the keypad — everything is computed locally in your browser.
How It Works
Tap the buttons or type directly into the display, then press = or Enter. Use the DEG/RAD switch to choose how trig functions interpret angles. AC clears, ⌫ deletes the last character.
When to Use It
Use it for homework, science and engineering, quick everyday math, or whenever you need more than a basic calculator.
Frequently Asked Questions
- Does it follow order of operations?
- Yes. It respects standard precedence (parentheses, powers, then × ÷, then + −) so expressions evaluate the way you'd expect.
- Degrees or radians?
- Toggle the DEG/RAD button. Trigonometric functions use degrees by default; switch to RAD for radians.
