I never memorized the quadratic formula, and I did OK.

  Did you go to school in the US in the last 2-3 decades?

    Once you start calculus they let you use a real calculator
    • whimsicalism 4y ago
      That may be true, but in the US there are typically math courses before calculus.

        But then we get a calculator.

          Maybe we went to radically different schools but I certainly had to calculate by hand using the quadratic formula countless times where calculators were not allowed to be used. Anyway it distracts from the point so it's not relevant.

          Even then, it is typically not a symbolic calculator so if your answer is a closed form function of variables, you're SOL with a TI-84.

    No, the UK. But completing the square only takes a minute.

      Try completing the square when the coefficients are variables :)
