please explain Base 16

[goofymcdooperface]

So today in Computer science we where learning about binary code. and the teacher taught us Base 2 but he also mentioned base 16 . what I'm wondering is how does it work does it go like this 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 10 and keep repeating or does it go like 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 100 or is there something else

Well google would answer this for you, or your text book probably.

But it goes like this

0 1 2 3 4 5 6 7 8 9 A B C D E F
