Uh, I am a math teacher. Sorry to say, I don't work much with groups. I took
one required course in Abstract Algebra, and then went on to do probability
and analysis, and a small bit of numerical methods. Abstract algebra is more
for the theorists and purists. I'm more interested in the practical
application of math (although I enjoy the theory and beauty of it, as well).

Here is a nice page with a lot of Algebra definitions and theorems on it:

If I get a better answer to "What are groups good for?", I will share.
