Finally Getting Two's Complement

Did you calculate the 9's complement of 4583 in your head? I see that 5416 has individual digits that line up with 4583 to each equal 9, but I'm not clear if this is a coincidence that happens to work for this number, or if this is the way to calculate an arbitrary N's complement value.

That is exactly the 9‘s complement. The digits add up to 9.

I thought there was more to the calculation of N's complement. Something about adding one to the result. It doesn't seem like something you can easily perform using inspection.
