I'm not sure that this aids Joanna's point, but on a more elementary level (that is to say i was taught this in elementary school) the truth of 2+2=4 is conditioned on the assumption of the density of real numbers. Otherwise 2+2=4 is not true by definition. i.e., if 2 (as in "2 percent of the vote") stands for all values between more than 1.5 and less than 2.5, then 2+2=4 will often be false.
