How it works
This calculator converts both hexadecimal inputs to decimal, performs the selected arithmetic operation, and then converts the result back to hexadecimal.
Example:
A3 in hex = 163 in decimal
FF in hex = 255 in decimal
Examples
- A + 5 → F
- 10 + 10 → 20 in hex
- FF − 1 → FE
- A × 10 → A0
