The number that comes after the plus or minus sign is how significant of a favorite or underdog the teams are, regarding points. In the first game, the Bengals are a 1.5 point underdog. This means that the sportsbook thinks the Bengals are going to lose the game by 1.5 points. This means, by default, that the Chiefs are a 1.5 point favorite. This means the sportsbook thinks the Chiefs are going to win the game by 1.5 points.
When wagering on a driver matchup, both drivers involved must start the race (cross the finish line) otherwise the wager is "No Action" and the money is refunded. In a case where the starting driver is replaced during the race with another driver from the same team (same car), the position the new driver finishes in will be awarded to the original driver. This holds for wagering on win odds and driver matchups.

### Apply the money line. It's easiest to think of money lines in relation to \$100. A minus sign means you have to bet that much money in order to win \$100; a plus sign means that a \$100 bet will return that much money. If you bet on Chicago at -110, you'll have to wager \$110 in order to get back \$100 (plus your original \$110). If you bet on Detroit at +145, then a \$100 bet will give you \$145 (plus your original \$100).

###### You should already know that the Eagles are the favorite to win and that you should expect less than even money on a correct pick here. You should also know that the Falcons are the favorite, and you should expect better than even money on a correct pick here. Having this in mind every time before you start your calculations will protect you from making a mistake and calculating the completely wrong direction.

One of the most basic concepts when it comes to betting on sports, especially football and basketball is the pointspread. Even people that do not bet on sports understand what it means when they read or hear that New England is a seven-point favorite against Miami. While reading a pointspread and understanding what they mean is a very basic sports betting concept, there is still more to these numbers than meets the eye.
Have you ever heard of moneyline betting? It's an American term that's traditionally associated with betting on the major US sports. These wagers are available in other parts of the world too, but they're typically referred to as win bets. The same principle applies though. When you correctly select which team will win a match, you'll get paid out at the relevant odds.
We’ve already covered that a moneyline bet is easy to make and is the most popular type of sports bet for beginners and for professional bettors. Now let’s talk about exactly what it is. A moneyline bet is a sports betting wager on which team or person will win a game or sporting contest. Simple as that. When you make a moneyline wager, you are betting on who will win a contest. It doesn’t matter how they win, by how many points, goals, or runs they win, or how long it takes them to win. All that matters to win a moneyline bet is that the team or person you bet on is victorious.
Apply the spread. In point-spread betting, the actual final score of the game is only the starting point. Say Chicago beats Detroit 24-17. Because Chicago was the favorite, you subtract the point spread from its final score. That's the purpose of the minus sign in the spread. The spread was 6, so you take 6 points away from Chicago's point total, giving you an "adjusted" score of Chicago 18, Detroit 17. If you'd bet on Chicago, you'd have won the bet. Now, say Chicago won the game 20-17. Subtracting the 6 points from Chicago's total gives you a final score of Detroit 17, Chicago 14. If you'd bet on Chicago, you'd have lost.
They do this by manipulating the lines to entice action where they need it. If they have too much action coming in on one team, they will adjust the lines to pay out less for that team to deter more bets. At the same time, they will adjust the line for the other team to pay out more to entice more action on that side. This dance continues until the game starts to try and get the correct amount of money on each side of the contest.
There's another reason to bet the underdogs on the moneyline as well. If your handicapping has made you feel very strongly that a poor team is due for a big win then the moneyline allows you to profit much more handsomely from your conclusion than a point spread bet does. The moneyline, then, is a powerful situational tool for people who closely follow the NBA.
It's also important to consider whether or not there's any correlation between the point spread and the betting total. If they are, a parlay wager is a good way to get maximum value. For example, a college football point spread +24.5 parlayed with under 48 points in the same game might be a great parlay bet. If the +24.5 team covers the point spread, then there's an increased chance that the game also goes under the posted total of 48.
In this example, we have a favorite to win, and an underdog. The Packers are the favorites, and that is shown by the (–) value in front of the 6. Underdogs are represented by the (+) value.  The 6 point value is how many points either team could win, or lose by. If you think the Packers will win by MORE than 6 points, then you’d bet on the favorite in this case, meaning that the Packers have to win by 7 or more points in order for you to win your bet.
