#FAQ
How do I add hexadecimal numbers? ▾
Enter two hex values and select the add operation. The tool converts them to decimal internally, performs the arithmetic, and displays the result in both hex and decimal.
What characters are valid in hexadecimal? ▾
Hexadecimal uses digits 0-9 and letters A-F (case-insensitive). Each hex digit represents 4 bits, so two hex digits represent one byte (0-255).
