OnSciCalc evaluates operations strictly in mathematical sequence:
Multiply a number by itself. 5^2 evaluates to 25.
Angles measured in radians or degrees. cos(pi) in RAD is -1.
💡 Toggle the 2nd button for shifted functions: sin⁻¹/cos⁻¹/tan⁻¹ (inverse trig), ∛ (cube root), x³ (cube), eˣ (exponential), 10ˣ (power of 10).
Evaluates automatically to 3 * (4+2) = 18.
ln stands for natural log (base e). ln(e) evaluates to 1.
Multiplies all positive integers down to 1. 4! evaluates to 24.
