The puzzlement of a maths illiterate

First off my perspective. I have never had any facility for maths, in fact I've been clinically diagnosed as suffering the mathematical equivalent of dyslexia, discalcula.

I'm able to handle philosophic abstractions with ease until something like the notation used in linguistic analysis rears it's ugly head. Which leads me to my question.

I notice, especially when physicists and cosmologists discuss maths, many are attracted to what they term a particular theorie's "mathematic elegance".

Putting aside for now their frequent assertion simple formulae will be a necessary and sufficient explanation of 'a theory of everything' can anyone please explain( to a moron

such as myself) how a formula can be 'elegant'. More significantly how and why could one be ugly?
