> Math class does not teach practical knowledge such as personal finance or health.

It teaches you how to work in a quant shop

You don't need to know anything about finance or health to know how percentages and compounding work.

Besides, I knew nothing about construction when I discovered that the contractor I hired to pour a patio was overcharging me by 30%. All it took was a bit of geometry I learned in grade school.

Pay no attention to math in school and you'll be prey to every scammer who did, and you'll never realize it.
