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:
3·103 + 7·102 + 2·101 + 4·100 = 3000 + 700 + 20 + 4 = 3724
For a 4 letter number (such as your name) in your base 26 system:
m·263 + a·262 + r·261 + k·260 = 12·263 + 0·262 + 17·261 + 10·260 = 211,364
