I didn’t learn how much it costs to raise a kid or what an affidavit is, but I spent days on what the quadratic equation is: negative b plus or minus the square root of b squared minus 4ac over 2a. That’s insane; that’s absolutely insane. They made me learn that over basic first aid or how to recognise the most deadly mental disorders or diseases with preventable causes or how to buy a house with a mortgage, if I could afford it, because abstract maths was deemed more important than advice that would literally save thousands of lives. But it’s cool, because now I could tell you if the number of unnecessary deaths caused by that choice was prime.
