Hmm, maybe a hint is in order?
Another equation would be:
4+7 = 233

Another similar puzzle would be:

1+4=5
2+5=7
3+6=11
6+7=?

Cheers!

Can it have more than one answer? I think I may have come to the same conclusion as the last guess that was made.
Spoiler:
18, 27, 36, 45

If it's one of those, I'm not sure how to narrow it down to a specific one?
