It refers to the base system used in math. We use base 10 for most everything. Binary is a common base 2 system used in computers. 1 = on 0 = off. Hex is 16 base (numbers 0-9 and A-F) Programing computer chips is often done in hex. (16bit)
It is best to understand the diffences and learn how it works by starting with converting base 2 to base 10. There are lots of internet sites you can search for on how to do base conversions. Enjoy!

Hexadecimal is a base 16 number system. The number system you were taught all through out school is base 10, that is, 0 - 9. In hexadecimal, the numbers would be 0 - 9 and a - f. A = 10, B = 11, C = 12, etc, up to F = 15. So, in a base 10 system, the number '10' is 'Ten'. In hexadecimal, the number '10' is actually 16. This is quite brief and their are several excellent websites that discuss hex in detail. As for when you would use hexadecimal, it is mainly used in programming.
As for Octal, octal is base 8 number system, that is numbers 0 - 7. So in the example above, 10 decimal is 10, 10 hexadecimal is 16 decimal, and 10 octal is 8 decimal.
Again, do a search for both hex and octal on the web as their are several good tutorial sites that will cover this in more depth than the brief explanation above.

In mathematics and computer science, base-16, hexadecimal, or simply hex, is a numeral system with a radix or base of 16, usually written using the symbols 0–9 and A–F or a–f.
The octal numeral system is the base-8 number system, and uses the digits 0 to 7.
I use hex for color on web page. Outside of computer you only need to learn it, to understand how to change from one number system to another. Kind of like knowing what is a milligram.
In color (HTML) there is 16 different shade of red,green,blue add them together and you get more colors then the eyes can see.
00ff08+ no red all green and half blue.
ffffff is all red all green and all blue makes white.
when does 1+1=10 Binary

Hexadecimal numbers are used by your comp. It has a base 16. 0-9 and a-f. You convert binary numbers into these or the other way around. Binary is like 10101100. 1and 0 stand for on and off. You comp. uses these. Its in math and comp. science!
