About the Scientific Calculator
Type an expression like sin(30) + sqrt(16) and get the answer immediately. Supports arithmetic, powers, parentheses, factorials, the constants pi and e, and functions like sine, cosine, square root, and logarithms, with a degrees/radians toggle.
How it’s calculated
Standard order of operations (PEMDAS): parentheses, exponents, multiplication/division, then addition/subtraction, with functions applied to their arguments.
Example calculation
sqrt(144) + 5^2 evaluates to 12 + 25 = 37.
Frequently asked questions
Which functions are supported?
sin, cos, tan and their inverses, sqrt, cbrt, ln (natural log), log (base 10), log2, exp, abs, floor, ceil, and round — plus the constants pi and e and factorial with !.
Degrees or radians?
Both — use the angle toggle. In degree mode, sin(30) is 0.5; in radian mode it's about −0.988.
