Scientific Calculator
Calculate arithmetic, powers, roots, trigonometry, logarithms and factorials with degree/radian modes and expression history.
Scientific calculator
Supported operations
Use + − × ÷, powers (^), factorial (!), percent (%), pi, e, ans, roots, logs, trigonometry and inverse trigonometry. Functions take parentheses; min, max and pow also accept comma-separated arguments.
DEG/RAD applies to trigonometry. % divides the preceding value by 100. Examples: 2^3^2 = 512; -2^2 = -4; 200*10% = 20.

About Scientific Calculator.
How scientific is calculated
Evaluates expressions using a restricted mathematical parser with standard operator precedence. Powers are right-associative; % divides the previous value by 100.
What the result means
Calculate arithmetic, powers, roots, trigonometry, logarithms and factorials with degree/radian modes and expression history.
Assumptions and scope
Angles use the selected DEG/RAD mode. Results use floating-point arithmetic; displayed values are rounded to 12 significant digits.
Using the calculator
Enter an expression or use the keypad. Choose degrees or radians for trigonometry, then calculate. Calculations run in your browser. No account is required.
