Hello users of brainden, I got to know this site from one of my friends said that you guys helped him solve a problem he was stuck on. Well, there is this one problem I have been trying to solve for hours right now, and I can't seem to get the answer to it. Would you mind helping?

Explain why m + n = 15.
