How to use Scientific Calculator
The Scientific Calculator evaluates mathematical expressions typed as text. You can use standard operators (+, -, *, /), exponents (**), and functions like sqrt(), sin(), cos(), tan(), log(), ln(), abs(), floor(), ceil(), and round().
Use pi for the value of pi (3.14159...) and e for Euler's number (2.71828...). Trig functions (sin, cos, tan) accept degrees.
Expression syntax
Use standard math operators: + - * /. Use ** for exponents. Parentheses work as expected: (2 + 3) * 4 = 20.
Examples
sqrt(144) = 12. pi * 10**2 = 314.15. sin(30) = 0.5. log(1000) = 3.
