When betting on MLB Toto, the numbers with plus (+) and minus (-) signs that you often see on casinos or Toto sites indicate the team's odds. The plus sign (+) indicates the underdog team, and the minus sign (-) indicates the favorite team. The underdog is expected to be a team with a low probability of winning, and the favorite is considered a team with a high probability of winning. https://www.nfl-news.org/kr/how-to-use-mlb-toto/
