About the scientific calculator
This calculator works like a handheld scientific model. Type an expression with the on-screen keys or your keyboard and it follows the normal order of operations: brackets first, then powers and roots, then multiplication and division, then addition and subtraction.
It includes sine, cosine and tangent with a degree or radian setting, their inverses, natural and common logarithms, powers, square roots, factorials, the constants π and e, and memory keys. Very large or very small answers switch to scientific notation automatically.
Nothing you type is sent anywhere. Expressions are parsed and evaluated safely in your browser.
Formula
- sin, cos, tan work in degrees or radians: radians = degrees × π ÷ 180
- ln(x) is the natural logarithm (base e); log(x) is base 10
- n! = n × (n − 1) × … × 1
Example
Enter 2 × (3 + 4)^2 and press equals. Brackets give 7, the square gives 49 and the product is 98. Switching to degree mode, sin(30) returns 0.5.
