About Hexadecimal Math
The hexadecimal system (Base 16) is a positional numeral system with a radix, or base, of 16. It uses sixteen distinct symbols: 0-9 to represent values zero to nine, and A-F to represent values ten to fifteen.
Arithmetic in Hex
Hex arithmetic works similarly to decimal, but carries happen when the sum reaches 16 instead of 10.
- Addition: 9 + 1 = A, F + 1 = 10 (16 in decimal).
- Subtraction: 10 - 1 = F.
Common Uses
Hex is primarily used in computing because it is a more human-friendly representation of binary-coded values. One hex digit represents exactly four binary digits (bits), also known as a nibble. Two hex digits represent one byte (8 bits).
- Color Codes: Web colors are often defined as #RRGGBB (e.g., #FFFFFF for white).
- Memory Addresses: Computer memory locations are typically displayed in hex.
? Frequently Asked Questions
