Microsoft Word Mobile

I know nothing about using Microsoft Word on my Android Phone. Today I was doing somethings in another app that required the degree symbol. I opened up Word on my desktop, inserted the symbol, then did a C/P into the app. I decided to open Word Mobile to see if I could accomplish the same when I was out and and about. Much to my chagrin I see that I am not able to insert any symbols, equations and other things, but no symbols. Is that correct or am I missing something?
