How to use the scientific calculator
- Tap the keys or type with your keyboard.
- Switch DEG / RAD for trig functions. Use 2nd for inverse functions.
- Press = for the answer, or Show steps to see the order of operations.
Frequently asked questions
How do I switch between degrees and radians?
Tap the DEG/RAD key at the top left. The current mode is shown on the display.
Can I use my keyboard?
Yes. Numbers, + − * / ^ ( ) and Enter all work. Backspace deletes, Escape clears.
