As of late, she has noticed that her students, who usually did quite well in math classes in high school and even college seem to still be innumerate when they reach her. I ask the percentage change between 8 million and 10 million and they give an answer of 200% and don't bat an eye. "Don't you see that that makes no sense?" she asks them. "Math is hard," they answer. If they have a formula, they can plug and chug an answer, but seem incapable of thinking about what it means.
Q: How is it Johnny can DO math (sometimes), but can't understand it?
