This has been argument I've had with people that always believe God can change math. Is it because math isn't taught right in school? It's like people think we derive mathematic principles from what we experience. Math is nothing but a set of necessary truths that precede each other. If you say one apple plus one apple makes two apples, that is an argument that is true regardless if God made it so a third apple pops out of nowhere when two apples meet. The statement 1 + 1 = 2 is true and 1 + 1 = 3 is false matter what experience shows us. Maybe this is why more abstract subjects in math is harder for American children. It's like they try and make sense of math from the real world when that isn't always useful.
