My accounting prof used to be a used car salesman. I was talking about that with him one day, and he said that a car dealership doesn't make money selling cars, but makes it selling financing.

The people who really pay through the nose for financing are people who do not grasp mathematics. He said it wasn't just a matter of them being taken advantage of - even when he explained the lower cost option, they'd insist on the higher cost one, based on faulty notions about math.

If you don't learn math, it's going to cost you plenty your whole life, and you won't even realize it. Math is necessary, even if you don't go on to get a STEM degree.

This also scales to the production level. Prior to the recent troubles, GMAC, the financing arm, was larger and more profitable than GM, the auto maker.


Well, based on your story, the important thing is not really to know math, but to not be incorrect about knowing math.
