Thing or nothing

The difference between a thing and nothing is not always clear.



As we deal here with mathematics, it sounds reasonable to call a thing 1 and nothing 0. That is quite logical. And moreover it becomes abstract. You would think that it should be clear whether the result of a calculation gives 0 or 1. But that is often not so simple.

You can also say: something is 0 or 1. If you have neither of these, there is nothing. This you need to write numbers in groups, if they contain only zeros and ones, as with

00   01   10   11

For this you can use spaces (so nothing).
