How to use Scientific Calculator
- Type an expression with your keyboard or tap the keys — e.g. 2sin(30)+√16.
- Choose DEG or RAD for trigonometry; press 2nd for inverse functions, eˣ, 10ˣ and more.
- Press = or Enter. Click any history entry to reuse it.
Questions
What order of operations is used?
Standard precedence: parentheses, then functions and factorials, then powers (right to left, so 2^3^2 = 2^9), then multiplication and division, then addition and subtraction. Implicit multiplication like 2π or 3(4+1) works too.
What is the difference between DEG and RAD?
DEG treats angles in degrees (sin 90 = 1); RAD uses radians (sin(π/2) = 1). The setting also controls what inverse functions like sin⁻¹ return.
Which functions can I type?
sin, cos, tan, asin, acos, atan, sinh, cosh, tanh, sqrt, cbrt, root(x, n), ln, log (base 10), log2, exp, abs, floor, ceil, round, nCr(n, r), nPr(n, r), plus ! for factorial, % for percent, and the constants pi, e and tau.
