How to Use
This calculator works like a standard scientific calculator:
- Enter numbers using the number pad or keyboard
- Apply operators (+, -, ×, ÷) between numbers
- Use parentheses for complex expressions
- Apply functions either before or after entering a value
- Use M+ to add to memory, M- to subtract from memory, and MR to recall memory
- Switch between Degrees and Radians using the Deg/Rad buttons
- Press = or Enter to calculate the result
