  Aktchually g gets simplified so it’s 5 > 2 for any value

    If you divide an inequality by a negative number you have to flip the sign.

    If you want to divide out the g before knowing if it’s positive or negative you need to make the case distinction.

    If you make the case distinction and one branch results in a false statement (5 < 2 in this case), you have disproven the original inequality, or at least discovered a constraint on the original inequality. Then you arrive back at FooBarrington’s statement :-)

    What if g is zero?

      Zero g is only available i special airplanes and in space, so not much of a worry for most people.

        Damn it! I was dreaming of one day scrolling Lemmy on a 0g connection. You ruined my dreams and I am sad now.

  What if g is a complex number?

    I don’t believe in such trite charlatanery

    “But I’ve learned about imaginary numbers in mathematics degree” well, that and $20 dollars will buy you an egg
