This link IS people being taught this. Don't be so dismissive of people whose lives are slightly different from yours.
However, I do feel it is necessary: even a limited person can improve by taking all of the juice of the most simple basic maths. I cheat, I use real world out of computer science simple solution in my code.
I noticed the "good student/developers" who were talented tend to solve problem the complicated way. And they developed both an agility and comfort zone out of it. So that my way of helping them saying: «hey man, programming is not about writing code, it is about solving problem with well known, basic understanding.»
You could call it «revenge». I call it irony. And if my words could hurt someone, since I am way more moderated than what I had to cope with, then I consider I am nice.
I won't apologize.
Like knowing non linear problem (like estimating the cost of resource "per user" on the cloud with all their "discrete" rough edged pricing plan) cannot be solved with linear algebra.
The cloud, the cost of IP transit (95th percentile) are defeating by nature any possible estimations. And still I see PhD and geniuses trying to code with linear equations the pricing based on the evolution of users. This is mathematically impossible.
So am I a genius, a dunce or what? I would be glad to know I am wrong, I would stop wondering.
If you have it, you are a genius.
A 14 yr old, it sounds like.
