Outs and Odds...
Now any of you that know me, know that I'm not a big maths fan. What I have realised though is that if I try to work out the outs and odds for every hand, even the ones I am not involved in, I could write it all into my memory and make it a habit, rather than have to worry about the maths on every hand.
You would normally only use the maths if you need to make a decision on whether to call a bet a not. If you think you have the best hand, raise. If you are unsure, use the maths to help make your descisions.
I do not profess to be an expert on this subject, but you can find all the info you need to know here:
That is the best article that I have found that explains the basics of what you need to know.
Hope Step 3 gives you positive results.
