y+3-5y+6y
1y take away 5y leaves you -4y then add 6y leaves you 2y
so you have 2y +3

Basicallyyou just count up your y's first. So 1-5+6 leaves you with 2y and then you have the + 3 sitting there so you put those together into 2y+3. But now you have a problem because you have no equal sign so you can't solve for y. You should have 2y+3 = some number so that you can figure out what y equals. Without that, you're stuck with just a math equation without a solution vbecause y could be any number imaginable.

(y+3)-(5y+6y). Now FOIL it. First, Outer, Inner, Last. Just multiply it. I can't really explain it in detail on yahoo, but I believe the answer is y^-33y. By y^ I mean y to the second power. I can't do that in this little box.

What is the problem? Are you being asked to simplify? You haven't given us all the information. Is all of this equal to something?
Assuming it is simplification, combine like terms -
1(y) - 5(y) + 6(y) + 3 = (1 - 5 + 6)y + 3 = 2y + 3.
Think of this like the Ys are apples and the 3 is dollars. If someone gave you one apple and $3, then gave you six more apples, then took 5 apples back, what would you have? 2 apples and $3.
