      as many different styles of explanation as possible, because you get different intuitions from each.

      Arnold is IMO overreacting (perhaps for performative and political reasons) against the horrors of mid20C French mathematics.

      That era was something of a Grothendieck cargo cult, and did for mathematics education what Le Corbusier did for architecture. Still...

      Speaking as a perhaps-decent algebraist once upon a time who nevertheless is hopeless at both logic AND physics.

      IMO algebra is the hardest part of calculus & differential equations. Can't ever remember all the rules properly.

      Yes, in general the hardest part of learning layer n of math seems usually to be the complexity of layer n-1 that’s required.

      When you’re learning highschool algebra, the hard part is doing the arithmetic properly; in calculus it’s the algebraic manipulations.

      Yes, couldn't agree more. The theory of calculus seems simple, elegant even. But doing the algebra was very hard for me, very frustrating.

      I wish highschool calculus was taught intuitively with much more software support so you could see how functions behave as graphical changes

          and also all the complexity, especially with trig, should be dropped. It’s irrelevant and archaic; no one actually solves integrals nowadays

          all the important intuitions come from integrating and differentiating polynomials and exponentials; the rest is just hazing
