How to use Scientific Calculator
- Type an expression such as
2*(3+4)^2, or build it with the keypad. - The answer appears as you type. Press = or Enter to keep it in the history and use Ans to reuse it.
- Choose degrees or radians before using sin, cos or tan.
- Use Copy result to copy the answer.
About this tool
The calculator reads your expression with its own parser, so nothing is run as code. Operators are + − × ÷ and ^ (power). Multiplication can be left out in simple cases, for example 2(3+4) or 2pi. Functions need brackets: sin(30), sqrt(16), log(1000) (base 10), ln(e) (natural), cbrt(27), abs(-5).
Order of operations: brackets first, then factorials and percent, then powers, then multiplication and division, then addition and subtraction. Note that -2^2 is −4 because the power is worked out before the minus sign. Answers are rounded to 12 significant digits, so tiny floating-point errors such as 0.1 + 0.2 do not show.

Common questions
Degrees or radians?
Use degrees for everyday angles (a right angle is 90). Use radians for most advanced maths, where a half turn is π. The setting affects sin, cos, tan and their inverses.
What does % do?
It divides the number before it by 100, so 50% is 0.5 and 200*15% is 30.
What are the limits?
Factorials work up to 170. Results larger than about 1.8 × 10308 cannot be shown.
