Numerals were often distinguished from letters by putting a mark above them. Numerals in the thousands were written by putting a mark below them instead of above them.
Note that the alphabet was enhanced by the addition of 3 or 4 older letters: either stigma or digamma for 6; koppa for 90; and sampi for 900.
Names could be assigned number values as in the following example:
ΙΗϹΟΥϹ or ΙΗΣΟΥΣ (IHSOUS/Jesus) = 10 + 8 + 200 + 70 + 400 + 200 = 888
