Scientific calculator online
Type a whole expression — with brackets, powers, roots and functions — and the calculator evaluates it with the correct order of operations.
You can use + − · ÷ ^ with brackets and functions: sqrt, log, ln, sin, cos, tan, abs. Constants: pi, e.
The expression sqrt(144) + 2^5 evaluates to 44.
Formula
Available operations and functions: + − · ÷ ^, brackets, sqrt, log, ln, sin, cos, tan, abs, round and factorial. The constants pi and e are typed by name.
How we got there
Trigonometric functions work in radians. To use degrees, convert them first: degrees · pi / 180.
How to write expressions in a scientific calculator
- Put brackets wherever they matter
The calculator follows the order of operations, so 2 + 3 · 4 gives 14. If you meant (2 + 3) · 4, the brackets have to be there.
- Write roots as sqrt or a fractional power
sqrt(144) and 144^(1/2) both give 12. For higher roots use 1024^(1/5).
- Mind the minus in front of a power
−2^2 reads as −(2²) = −4. If you want the square of a negative number, write (−2)^2 = 4.

Frequently asked questions
Write sqrt(144) or √144. For higher roots use a fractional exponent, such as 1024^(1/5).
Radians. To get the sine of 30 degrees, enter sin(30 · pi / 180).
The calculator returns a dash when the expression cannot be evaluated — a division by zero, an unclosed bracket, or an unknown function name.
