I'm suprised no one mentioned that some logic views the glass as half full and some logic views it as half empty....
I think we need more students coming this way, some of you need some practice....
Basically it's a "Logics 101" question. You can work with the 1s, what most people do, or you can make it hard on yourself and work with the 0s as schoolteachers like to do. And yes, some technology is based on negative logic, because of the design.
Kind regards,
