All the words until the last must define the notation used in the expression after the last blank. Every one of these generate nothing, because the last "word" is not a mathematical expression, eg. " One divided by the smallest number which everyone ever had in mind." should be equal to "Mind.", and because there is no decent interpretation of that which would lead to a number, it is disqualified.

As for your comment, FA, the same apllies. "The last number used by humanity until now" would be equal to "now",  and because there is no decent interpretation of that which would lead to a number, it is disqualified.

And as for your comment, alemango, that is already written above.
