Is poetry math or mathematical?

Absolutely

My most difficult work I ever did made me aware of this around a tough editing I was doing at a Starbucks.  I was feeling the math so strongly I exclaimed to the man sitting next to me that I felt like I was doing math rather than writing which I found a bit disturbing.  All I know is that the problem solving had complex rules to strictly follow.  So it got very math like for me.  I WAS GLAD TO FINISH THIS PIECE!
