Hex number system question

Is there a point beyond Hex 11 where Hex numbers turn to alphabet again?

Do the hex numbers continue in decimal-line form beyond hex 11?

That is , 12,13,14,...

Hmm, let me just count a little for you in hex:

0, 1, 2, 3..., 8, 9, a, b, c, d, e, f, 10, 11, 12, ..., 18, 19, 1a, 1b, 1c, 1d, 1e, 1f, 20, 21, etc.

Does this make sense to you now?

To continue on that line of reasoning:

the hexadecimal number system (normally just written hex), is just base 16. Since we don't have 16 distinct numerals (that is, characters which represent numbers), we borrow the first 6 Latin letters:

0,1,2,3,4,5,6,7,8,9,a,b,c,d,e,f,10,...

Just like any base, 16^1 = 10, 16^2 = 100

so the number 2af means 2 *16^2 + a*16^1 + f*1 =
2*256 + 10*16 + 15 =
512 + 160 +15 = 687 in base 10
