| 6.9. Counting while comparing

Lastly we can also ask for a more specific number of possibilities, like so:

> if two women are carrying animals
> if at most three doors are open
> if fewer than 10 portable containers are closed
> if all but two of the devices are switched on

Likewise for "less than", "more than", "at least", "all except". Something to watch out for is that

> if two doors are open

will be found true if there are (say) three open doors: after all, if three doors are open, then certainly two doors are. So this is not quite counting. We can be more precise by writing

> if exactly two doors are open

The "all but" counts - say, "if all but two doors are open" - are exact: if, in fact, all of the doors are open then this will be found false.

Lastly, note that the "the" in text like "two of the doors" matters: without it, the phrase will not be recognised as a requirement on the number. (This is to make sure that names of things like "two of hearts" are not misinterpreted.)
