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

  • Base-16 numbering system.
  • The letters A, B, C, D, E, F represent 10, 11, 12, 13, 14, 15 respectively.
  • Typically prefixed with '0x' in programming languages like C and JavaScript.

Applications

  • Memory addressing and debugging.
  • HTML/CSS web colors (e.g., #FFFFFF).
  • Encoding text and files (e.g., base16/hex dumps).
