What functions does this scientific calculator support?

It supports basic arithmetic, trigonometric functions (sin, cos, tan and their inverses), logarithms (ln, log), square root, exponents (x^y), factorial (n!), pi, e, and parentheses. It also includes memory functions (MC, MR, M+, MS) and RAD/DEG mode.

What is the difference between RAD and DEG mode?

RAD mode calculates trigonometric functions using radians, while DEG mode uses degrees. One full rotation is 2π radians or 360 degrees.

Trig functions, logarithms, exponents, factorials, π, e — it's all here. Whether you're doing homework, prepping for an exam, or just need something more powerful than a basic calculator, this has you covered. And yes, it handles parentheses properly (looking at you, viral math problems).

Memory and History

Store a value with MS, recall it with MR, add to it with M+, or clear it with MC. There's also a scrollable history so you can look back at previous calculations without re-entering everything. Switch between RAD and DEG mode depending on what your math requires.

Quick Tip

You can also use your keyboard — numbers, operators, Enter to calculate, Escape to clear. Way faster than clicking buttons if you're on a desktop.
