How to bet
Betting sites often use the Moneyline format to represent odds. The odds are either negative or positive where a negative value (for example -250) usually indicate the favourite and quotes how much that must be bet in order to win $100.
A postive value (for example +150) usually indicates the underdog and quotes how much that would be won when betting $100.
Example:
At UFC 77, Anderson Silva was the favourite at -185 against Rich Franklin at +190.
If you had bet $100 on Silva and Silva won then you would have gotten $154 back (initial bet included).
Betting $100 on Franklin would have given a total of $290 back (initial bet included) if Franklin won the fight.
