❓ Frequently Asked Questions (FAQ)
📌 Can I use this calculator on my phone?
Yes! It’s fully responsive and mobile-friendly.
📌 Does it support degrees and radians?
Yes. Tap Deg or Rad to switch between degree and radian mode for trigonometric functions.
📌 What does the Ans button do?
It recalls the last calculated answer, letting you use it in a new expression without retyping it.
📌 How does the memory work?
M+: Adds the current display value to memoryM-: Subtracts from memoryMR: Recalls memoryMC: Clears memory
📌 Why is eˣ different from EXP?
eˣ: Raises Euler’s numbereto the power ofxEXP: Scientific notation, e.g.,3EXP4=3 × 10⁴
📌 What’s the difference between ln and log?
ln: Natural logarithm (basee)log: Base-10 logarithm
