Hi guys, I'm so confused about max of two points that they are the same, I mean if I have max(5,5) => 5

but I dont understand this, because max means the greatest point upon the points we have, but we have 5 ,5 so we don't have maximum point because none of two points (5,5) greater than each other, so the max() should return 0 and not 5 because the two points are not greater than each other , they are equal, so we have no greater one than the other one ... so the max should return 0 ..but sounds it's wrong as the video I watched for learning .. so anyone can help how can I define the max function?
