How the scientific calculator works

Type an expression with the keypad or your keyboard and press = (or Enter). The calculator follows the usual order of operations: parentheses first, then powers and roots, then multiplication and division, then addition and subtraction. A preview of the answer shows while you type.

Trigonometry uses degrees or radians (switch with Deg and Rad). Inverse functions return angles in the same unit. ln is the natural log (base e) and log is base 10. xʸ raises to a power, ʸ√x takes the y-th root (type y first, then ʸ√x, then x), and EXP enters a power of ten, so 3 EXP 5 means 3 × 10⁵.

Ans holds your last answer. M+ adds the current answer to memory, M− subtracts it and MR recalls it. Results show up to 12 significant digits and switch to E notation for very large or very small numbers.
