    a + max(b,0)

    max(d, c, 0)

    If S is a set then \max S means the biggest element in S. So for example \max \{ 1,9,2,4 \} = 9.

    So when you see something like \max \{ 0, a, b, c, d \} it means the "largest positive number out of a,b,c,d, or 0 if they're all negative", and so on.

    What if i have:

    max(0, -a)

    max(-a, 0)

    Is there a difference between the two? I don't understand the purpose of the '0'.

    There is no difference. If a were positive, then -a would be negative and max(-a,0) would be 0. Otherwise max(-a,0) = -a
