Common questions and solutions

❓ FREQUENTLY ASKED QUESTIONS

Q: What's the difference between DEG and RAD modes?
A: DEG mode uses degrees (360° in a circle). RAD mode uses radians (2π radians in a circle). For trigonometry, use DEG for angles like 30°, 45°, 90°. Use RAD for calculus and advanced mathematics.
Q: How do I calculate factorial?
A: Use the n! button. Factorial is the product of all positive integers up to n. Example: 5! = 5×4×3×2×1 = 120. Factorials are used in probability and combinatorics.
Q: Can I use keyboard to input calculations?
A: Yes! The calculator supports full keyboard input. Use number keys, + - * / for operations, Enter for equals, Escape to clear, and Backspace to delete.
