About the scientific calculator
A scientific calculator handles advanced math beyond basic arithmetic — trigonometry, logarithms, powers and roots, factorials and constants like pi and e. Type or click an expression and get an accurate result instantly. It is ideal for school, engineering, science and everyday calculations, and runs entirely in your browser.
How Scientific Calculator works
How to use the scientific calculator
- Enter an expression using numbers, operators and functions.
- Use functions like sin, cos, tan, log, ln, sqrt, powers (^) and factorial (!).
- Get the result instantly; use parentheses to control the order of operations.
Functions and constants
It supports trigonometry (sin, cos, tan and inverses), logarithms (log base 10 and natural ln), exponents and roots, factorials, and constants π and e. Switch between degrees and radians for trig.
Accurate and instant
Calculations follow standard math order of operations, so complex expressions evaluate correctly without manual steps.
Common uses
- Solve trigonometry problems
- Calculate logarithms and exponents
- Work out powers and roots
- Compute factorials and combinations
- Use pi and e in calculations
- Check homework and exam answers
- Do engineering and science math
- Evaluate complex expressions
