The usual way to represent bases greater than ten is to use 0 - 9 then A, B, C, etc. for 10, 11, 12, and so on. The hexadecimal (base 16) system, for instance is:

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

Your system is a bit unconventional in that sense, but since it's just for fun I guess it's OK. Numbers have place value in any number system. For instance, the number 3724 in base 10 is:

3·10^{3} + 7·10^{2} + 2·10^{1} + 4·10^{0} = 3000 + 700 + 20 + 4 = 3724

For a 4 letter number (such as your name) in your base 26 system:

m·26^{3} + a·26^{2} + r·26^{1} + k·26^{0} = 12·26^{3} + 0·26^{2} + 17·26^{1} + 10·26^{0} = 211,364
