Question

what'S EEO+EOO=OEOE all thoes in numbers

Answer 1

Thinking about what this "thoes" could mean "These Os and Es; these; those; The Os/Es" hurt my brain.

Anyways,
If it's in base 10, then we have that:
\[
2\cdot O\equiv E\mod 10
\]And that:
\[
E+O\equiv O \mod 10
\]We can solve this by saying:
\[
E=0, O=0
\]Or
\[
E=0, O=5
\]But the latter doesn't hold, so E and O must equal zero.
