Calculus could be taught with simple rules: d/dx x^n = nx^(n-1)... simple.

But if you never learned LIMITS then you don’t understand WHY this is true.

or why d/dx e^x = e^x (weird......!!!)

Calculus could be taught with simple rules . . . as long as you just use a computer program which will do all the work.

. . . the problem then is reduced to making sure you are asking the computer the right question. That is always the issue in the real world. But if you don’t know the lingo, you can’t ask the right question.
