s = 5 s+= 3 means s = 8 in other words it's s = s + 3 you add the right veriable to the left which means since our s = 8 now doing s -= 4 will subtract 4 from s so now s = 4

"x+=y" is the same that "x=x+y". "+=" is a abbreviation of a sum where one term (x) will receive your value more the value of the "y".

Gotta say I'm impressed by how nice this community is. I came here and almost expected commentors ranting at the asker for not having read the explanation earlier in the lessons, but you go ahead and simply explain.
