About this calculator
Choose degrees or radians for angles. Multiplication can be implied, so 2pi and 3(4 + 1) work.
How to use it
- Type the expression.
- Choose degrees or radians.
- Read the result.
The formula
Order of operations: brackets, powers, × ÷, + −
- ^
- power (also **)
- sqrt, cbrt
- roots
- sin, cos, tan
- trig functions
- log, ln
- base-10 and natural logs
- !
- factorial
- pi, e

Worked example
2^10 + sqrt(16) × sin(30)
- 2¹⁰ = 1,024; √16 = 4; sin 30° = 0.5.
- 1,024 + 4 × 0.5 = 1,026.
What the result means
Powers are worked right to left: 2^3^2 = 2^9 = 512.
Assumptions
- Real numbers.
Limitations
- Complex numbers and matrices are not supported.
Frequently asked questions
Does −2^2 equal 4 or −4?
−4: the power is applied before the minus sign, as in standard maths.
How do I enter π?
Type pi.
Are angles in degrees?
By default; switch to radians if you need them.
