NFL betting/beginner question

Probably a very easy question for someone/nearly everyone here to answer. Im planning on making like $500k+ on daily fantasy this year (lol)- Anyways, when I'm looking @ Vegas Odds, I see

483 Cincinnati -3 -10
484 Oakland 44½u -10


I know that Cincy is favored to Win by 3, I know that the O/U is 44½ points, what do the "-10's" mean?

I'm familiar with like +190/-210 (or something) as far as betting goes, but I have 0 clue what these 10's mean. Some of them have "EV" next to it as well (assuming even)

can anyone explain to me what this means? Ive tried Googling/Youtube, however the only thing Ive seen is what I already know (+150 - Bet 100 to win 150 or -150 bet 150 to win 100)

The juice they're charging maybe? I'm not sure really. Usually the juice will be in paranthases like (-110) with the online books

Yeah, I have no idea.. Thanks for the response though. I'm glad I'm not the only one thats a little confused by this..

it's the juice, looks like they're just doing it that way to save space. for ex. if you click the Pittsburgh/New England odds under William Hill where it says:

49½u-10
-2½ -10

it takes you to this page that has the juice in standard format of:

X spread/Y total (-110 juice)

they don't have parentheses for the juice, but i mean...that's definitely what it is.

Oh, okay. Thanks for clearing that up sir!
