I don't think it has anything to do with computers. Tests have had formula sheets for decades, the quadratic formula would typically be on there.

The importance has always been "how its applied." Tons of people failed classes despite knowing the formula. It has always been about the basic application.

I don't think many math tests consisted of "write down the quadratic formula" and that's it.

The point is more that before computers, you could at least make a somewhat reasonable claim that it's useful to know the formula in case you need to solve a quadratic - even if you don't understand the formula.

But nowadays, you can just feed the equation to Wolfram|Alpha (or Sage, or Mathematica, ...), so there is no point in blindly memorising formulas.

And I don't think I've ever had a formula sheet in one of my maths exams in school...
