make a condition with the equation module but i don't understand
how to do
i constated that the inlet "a" is 0 or 1 and when is 0 it sends the number strored in "b"
and when "a" is 1 it sends the number stored in "c"
but i don't know what is the function of the inlet "d"
i supposed that the "d" could be the add of c and b
but i don't understand how it works
so if somebody can give me an example a drawing
it helps me a lot to understand
thanx
