Lineman football plays?

i don't understand my plays fully and my first game starts in about 8 hours. please help, i need to know what the tackle on the offensive and defensive side does in the trap, dive, toss, i don't know what you do when the guy says front zero back scoop, and im not fully sure but when he says 30 31, 60 61, or 80 81 do you just get the nearest guy to you. also how to effectively p two people zoning on you to get to the quarterback. any help is appreciated thanks.
