Answer: P means "This statement is false"

then, P is a "function" of some statement,

if i write P (3> 1932) this could be read as:

3>1932, this statement is false.

You could see that 3> 1932 is false, so P (3>1932) is true.

Then you could se P (x) at something that is false if x is true, and true if x is false, so p is a negation.
