The primary reason to teach math is to instil a form of logical reasoning. For instance, Phytagoras theorem is typically the first introduction to formal proofs. It’s literally the antidote to much of the stupidity we are currently observing in the world.
Having said that, your response is particularly idiotic because Phytagoras theorem plays a crucial role in home improvement projects. The fact that you have never applied it in real life is likely why you cannot repair stuff in your house.
More generally, I use the knowledge I have attained from physics and mathematics when I repair stuff at home. Maybe the reason you have trouble with these things is because you didn’t pay attention in school?
Wasn’t there a candidate during the last election who wanted to legalise cannabis?
