Macro substitution is simple text replacement before it compiles. (28/square(4)) Replace square(4) with 4*4: (28/4*4) Now reduce according to order of operations (left to right in this case): (7*4) (28) Proper macro definition would fix it: #define square(x) ((x)*(x))

I'm no expert in C but it gives the expected result (1) when you enclose square(4) in parentheses; (square(4))
