Calculators
A full-featured scientific calculator with trigonometric functions, logarithms, powers, roots, factorial, and memory registers. Supports both degrees and radians.
Follow these simple steps to get instant, accurate results directly in your browser:
Select Degrees (DEG) or Radians (RAD) for trigonometric operations.
Use the on-screen keypad or your keyboard to input equations.
Press '=' to compute the answer and view calculation history.
The Scientific Calculator is an advanced mathematical computing environment that evaluates trigonometric functions, logarithms, exponentials, roots, factorials, and algebraic expressions with high precision.
Supporting both Degree and Radian angle modes, the calculator implements standard mathematical order of operations (PEMDAS/BODMAS) with parentheses nesting. It supports standard scientific functions: sin, cos, tan, inverse trig (asin, acos, atan), natural log (ln), base-10 log (log), exponentiation (x^y), square roots, constants (pi, e), and percentage operations.
Calculations run directly on your browser's JavaScript V8/SpiderMonkey mathematical engine with zero server delay.
Parentheses -> Exponents/Roots -> Multiplication/Division -> Addition/SubtractionCalculates nested algebraic expressions adhering to international IEEE 754 floating-point arithmetic standards.
Evaluate: 3 + 4 * 2^3 / (1 - 5)^2 Step 1 (Parentheses): (1 - 5) = -4 Step 2 (Exponents): 2^3 = 8 and (-4)^2 = 16 -> Expression: 3 + 4 * 8 / 16 Step 3 (Multiply/Divide left-to-right): 4 * 8 = 32 -> 32 / 16 = 2 Step 4 (Addition): 3 + 2 = 5.0.
