Scientific calculator
A full scientific calculator: trig, logs, powers, roots, factorials and memory, with keyboard support.
Tips
Use INV for the inverse functions: sin⁻¹, cos⁻¹, tan⁻¹, eˣ and 10ˣ. Ans reuses your last answer, and pressing an operator straight after = carries the answer on. Tap any line in the history to bring it back. Multiplication can be left out: 2π and 3(4+5) work. EXP enters powers of ten, so 6.02 EXP 23 is 6.02 × 10²³.
Order of operations
Brackets first, then powers and roots, then multiplication and division, then addition and subtraction. −2² is −4, because the power is worked out before the minus sign; type (−2)² for 4.
