First (wrong) try:

Supposing AND stands for "sum" I think:
0615
Because i changed all letters with corresponding ASCII code, and sum every letter in the word (147 + 0 + 0 + 144 = 291 and 3 + 166 + 1 + 154 = 324). Adding them gives 615

Changing even digits to ASCII, result is increased by 240, giving 855
