How the scientific calculator works
Type a complete mathematical expression and press Evaluate. The calculator parses the whole expression at once — respecting standard order of operations (parentheses, exponents, then multiplication/division, then addition/subtraction) — and returns the result. Angle-based functions like sin, cos and tan read your selected degrees / radians mode.
Supported functions and operators
trig: sin cos tan asin acos atan
logs: ln(x) log(x, base 10) exp(x)
roots: sqrt(x) cbrt(x) x^y
misc: abs(x) n! (factorial) pi e
Trigonometric functions assume the angle is in degrees by default, matching how most people enter angles; switch to radians for calculus-style work where π radians = 180°.
Worked example
Evaluate sin(30) + √16 in degree mode:
sin(30°): = 0.5.
√16: = 4.
Sum: 0.5 + 4 = 4.5.
Tip: use parentheses generously.
2^3^2 evaluates right-to-left to 512, but (2^3)^2 is 64 — being explicit avoids surprises.
