How do I switch between Degrees and Radians?

Click the DEG or RAD button located at the top-left of the calculator controls bar. When DEG is highlighted, all trigonometric functions evaluate angles in degrees (e.g. sin(90) = 1). When RAD is active, angles are evaluated in radians (e.g. sin(π/2) = 1).

How do the memory registers (MC, MR, M+, M-, MS) work?

MS (Memory Store) stores the current result into memory. MR (Memory Recall) inserts the stored memory value into your active equation. M+ adds the current result to memory, M- subtracts it, and MC (Memory Clear) resets the stored memory back to zero.

Does this scientific calculator follow the standard order of operations (PEMDAS/BODMAS)?

Yes. Equations are parsed following strict mathematical precedence: Parentheses first, followed by Exponents/Powers, Multiplication and Division from left to right, and Addition and Subtraction.

Can I use my physical keyboard to enter calculations?

Yes! You can type numbers 0-9, decimal point (.), basic arithmetic (+, -, *, /), parentheses (), exponents (^), Enter for equals, Backspace to delete, and Escape to clear (AC).

How do I calculate factorials (n!)?

Enter a non-negative integer and click the n! button. For example, entering 5 followed by n! computes 5 × 4 × 3 × 2 × 1 = 120.
