I said past the elementary level.
Even understanding things like compound interest don't require you to be able to do the computation itself.
Being bad with money is a complicated subject. It goes way beyond an understanding of math, hence why there are plenty of people who are good at arithmetic but still spend like idiots.
That's fair, on the second point, but I can only partially agree with the other.
There's no "shortcut" to real learning (i.e. developing an intuition, understanding, etc) besides practice, the closest maybe being cleverly developing new ways to teach.
We definitely don't need to teach those old mental math tricks anymore, but brains learn via practice (i.e. manual computation) to gain the fundamental understanding needed before using tools to skip those steps.
The only way I can imagine really not needing for normal life is if you can afford to pay someone you trust to understand it for you.
Again, beyond the elementary school level. So, how do all the poor people without higher level math skills survive?
You're being very patronizing right now. Probably because you, personally, rely a lot of math skills that the vast majority of people somehow manage to do without.
I hope you can realize that.
