It depends. If you want to study maths, yes. If you want to be a programmer:

[status, value] = add(a, b);

Is much more unparalleled-ly (?) readable from the perspective of how a computer actually operates. In reality, this:

uint c = (uint)a + (uint)b; // (to make that other guy happy)

is really:

c = (a + b) % (sizeof(uint));

in "C", which is less readable but far more accurate.
