About Hexadecimal Math
The hexadecimal numeral system uses 16 symbols: 0-9 and A-F. It is widely used in computing as a human-friendly representation of binary values.
Hex Addition
Add bits column by column. If the sum exceeds 15 (F), subtract 16 and carry over 1 to the next column.
Hex to Binary Relationship
One hexadecimal digit exactly represents four binary digits (bits), also known as a nibble. This makes hex to binary conversion direct and efficient.
Key Concepts
