How to use it
Type an expression with the keyboard or the keys, for example 2(3+4)^2, sin(30) or 15% × 2400. The answer is worked out on every key press; press = or Enter to keep it as Ans and add it to the history. Escape clears.
- Deg / Rad chooses whether angles for sin, cos and tan are in degrees or radians.
- EXP enters scientific notation:
3E8is 3 × 10⁸. - M+ / M− / MR / MC add the current result to memory, subtract it, recall it and clear it.
- Missing closing brackets are added for you, and a number next to a bracket or constant multiplies it (
2π,3(4)).
Order of operations
Brackets first, then factorial and percent, then powers (right to left, so 2^3^2 = 512), then the sign (-2^2 = -4), then ×, ÷ and mod, and finally + and −.
