CalculynHow it works
Type an expression the way you'd write it. Supported: + − × ÷, ^ for powers, parentheses, % (divides by 100), ! (factorial), sqrt, cbrt, sin, cos, tan, asin, acos, atan, log (base 10), ln, exp, abs, and the constants pi and e. Trig functions use the angle unit you pick.
Formula
Order of operations: parentheses → functions → powers (right to left) → × ÷ → + −
Example
2^10 + sqrt(144) × sin(30°) = 1024 + 12 × 0.5 = 1,030.

Frequently asked questions
Is -2^2 equal to 4 or -4?
-4. Powers are applied before the minus sign, matching standard math convention. Write (-2)^2 to get 4.
What does log mean here?
log is base-10 logarithm and ln is the natural logarithm (base e).
Degrees or radians?
Use degrees for everyday angles (a right angle is 90°). Radians are common in calculus and physics (a right angle is π/2).
