> struggle to accomplish much simpler (at least to me) tasks like proving that the product of two even integers is an even integer. I always see articles that claim I didn't do math in high school, and then people talk about things like this. I did this in high school. In the US. In 2001. Literally, one of our test questions was: (a) prove the product of two even numbers is even (b) prove the product of two odd numbers is odd (c) prove the product of an odd and even number is even And this wasn't regurgitating a proof we learned in class or had on homework, it was a question we had not seen before. Blanket statements about what people see and don't see in high school are worthless.
