Hexidecimal

Alot of people don't understand what hexidecimal is, when its a bit simple.

Hexidecimal can be two things.
It can be an RGB color value (eg: 00ffff, which would be red)
It can also be an offset value for hexidecimal code (eg: 0x0ffa3f)

Hexidecimal is an elongated version of standard numbering
Standard numbering goes as follows: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9
Hexidecimal numbering goes as follows: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F
So for example, A + B = 16

Hexidecimal offsets are used to show the location of a hexidecimal value within a file

For example, if it was 0x000001, It would be the very first hexidecimal value within a file.

Hexidecimal has two values, that together equal one value that you would see in a a file if you where to open it in notepad

For example, if the value is 00, it means that there is nothing whatsoever in that spot, and often acts as null, or a space.
Hope this helps you guys out who don't know what they are!
