That's what dads are supposed to teach you. Leave the trig, chemistry, etc., to the academicians. Can you imagine your dad teaching you calculus? Very few dads could. And believe it or not you need the academic stuff for lots of jobs. Otherwise, prepare to dig ditches.
“ Can you imagine your dad teaching you calculus?”
I teach all my friends kids all manner of science, physics, engineering and algebra through calculus, diff eq, statistics. High school algebra is the worst. When kids are having trouble, I ask them to show me what their teacher taught them. I am always appalled at how obvious it is that the math teacher does not understand the first thing about mathematics. I also find it astonishing that they do not seem to teach english, or spelling or grammar, and history is either not taught at all or revised to the point of absurdity. Also things that were general knowledge or common sense in the 70s and 80s are simply gone.
I can tell you that I make very good money. More than a lot of engineers and scientists. I have never had the need for more than basic math and geometry in my entire adult life. I would have LOVED real-world classes in high school but I was stuck in a school that was basically college prep. Hated it, and so did most of my friends. Turns out most of my blue-collar friends are business owners, hard workers and tradesmen. Making good money, and were debt free, unlike most of our classmates.
Most jobs out there, including trades and technical careers don’t need much beyond that, and that can be learned on the job. And they make good money.
Oh yeah. I have an office job. Not digging ditches.
