Hexadecimal in the Real World
Hexadecimal is the language of computing, used everywhere from the colors on your screen to the data in your computer's memory.
Web Colors (CSS)
Hex codes like #FF3A8B represent colors by defining the amount of Red (FF), Green (3A), and Blue (8B) in a single string.
Memory Addresses
Computers use hexadecimal to display memory locations. It's shorter and more readable than the long binary strings it represents.
Networking
MAC addresses, which uniquely identify devices on a network, are written in hexadecimal format (e.g., 00:1A:2B:3C:4D:5E).

| Binary | Base-2 | 0, 1 | 11010 |
| Hexadecimal | Base-16 | 0-9, A, B, C, D, E, F | 1A |
Frequently Asked Questions
Quick answers to common questions about hexadecimal addition and how this calculator works.
What does "carry the 1" mean in hex?
In hex, you "carry the 1" when the sum of a column is 16 or greater. For example, if you add 9 + 8, the decimal sum is 17. Since this is over 15, you find the remainder (17 - 16 = 1) and carry a 1 to the next column. The result for that column is 1. So, 9 + 8 in hex is 11.
Why are the letters A-F used?
Because hexadecimal is a base-16 system, it needs 16 unique symbols for its digits. The standard decimal system only provides 10 (0-9). To represent the values for 10 through 15, the letters A through F were chosen as the standard single-character symbols: A=10, B=11, C=12, D=13, E=14, F=15.
