Let's be honest: advanced math is useful in programming contexts. Everywhere else, in 2023 you're using computer programs that will do the hard math for you.
Math is not about calculators or computers.
It is about modeling (e.g real world)
It is useful whenever non-standard, already modeled in your calculator problem apprears.
The real problem is you can cannot find a language which you don't speak, useful.
The only reason why things like Addition, Subtraction, Multiplication, Division come easily even to people without any education is because it has to become a part of their everyday vocabulary if you have to as little as start a lemonade stand. If Im not wrong Arabs arrived at algebra trying to workout inheritance laws from the Quran. Want to build a home, you can only brute force that much, eventually you are likely to invent the Pythagoras theorem, measurement techniques, myriad other geometrical methods.
All this is possible because if you have to do a thing, anything at all, well, you have to arrive at the most logically consistent formulation of the problem. That helps you to not only do it well, but do it right.
The real question there fore is introducing Math in a way it becomes a part of people vocabulary and general language.
Perhaps he didn’t and for me it is part of the problem to apply math. Even if you have figured out the model and trying to share conclusions/concerns/solutions you frequently asked “why”. Then you go to explain … and there they are lost and then reject/downvote your “bs, as they usually put it”
>Then you basically not only get better tools to operate (model) in real world, day2day life, but also it opens you doors to highly paid careers.
can you elaborate on how “it opens you doors to highly paid careers”?
one could be the ‘smartest person in the room’ but who cares?
Depends on the level of proficiency
Examples can be engineering or fancy financial related companies like Jane Street
Yes, calculating the right amount of fence is useful, but not only (as someone pointed out) you don't need a lot of math for that, people just take take a ruler on the plan, or count steps in field, going across the entire length, then estimate, and it works.
> estimation of 500km route arrival time while taking traffic statistics into the account
Who does this? How would you convince a friend to learn math in order to do this? What people do is they remember how long a 200 km route took and so they estimate the 2.5× longer path will take 2.5× more time.
We need examples of real world math applications, because such examples are scarce across the Internet.
