the function max is giving me the maximum number of the numbers in other words max(4,5) = 5 ; but what's confusing me is max(5,5)=5 why? whenever the values of the elements of max are equal I got confusion .. why max (5,5) is 5?! maybe I defined the "max" in inappropriate way? can someone please instruct me about its definition(max definition) because every time I see the values are equal I get confused to find maximum of them ..

thanks!!
