The -115 are the odds on the team to win the match. As opposed to having a goal-line, as in the example in Q 44, you can also bet the odds in soccer. An example here again from the English Premiere League would be if Manchester United was (-115) vs. Tottenham and you bet Manchester United you would have to wager $115 to win $100. And then all Manchester United would have to do is win the match for you to collect on your bet. If the match ends in a draw, or if the Spurs win then you would lose your bet.
