    I’m well familiar with math and the rules by which it works

    i know you won’t realise this because you never got past basic calculus, but this is a very funny statement to anybody that did

    they know all the “math rules” guys. which ones? ALL of them

    but okay these rules: where do they come from, then?

      Fortunately, the rules necessary to resolve the equation in this post are extremely elementary, so none of what you’re referencing has any bearing whatever.

      There are exactly three things to consider in here to determine priority: parentheses, multiplication/division, and addition. The addition happens first due to the parentheses, and the remaining is evaluated left-to-right. The only correct answer here is 16.

      All your deflection from your embarrassment at misreading a simple equation doesn’t detract from this.

        this would be like trying to tell a chemical engineer they didn’t know what they were doing based on your understanding of the atom as a ball of protons with electrons wooshing round it like they were moons

        very cute

        unfortunately, if you give the expression 1 / 2x to anybody who knows what they’re doing they’ll interpret it as 1 / (2x) because it would be absurd not to

        for reference, that’s why the calculator works like this. because it’s a tool designed primarily for people who actually know what they’re doing with numbers, so it works how they expect it to work

          And there you’ve proven exactly what I’ve been saying all along. 2x works the way it does because there’s a variable involved, and natural reading of that treats it as a single entity. There are no variables in the equation in the post, there are only definite numbers, parentheses, and simple mathematical operations. 8/2(2+2) is nothing more than 8/2×(2+2). There is nothing special about 2(…, this is not the equivalent of 2x.

            a natural reading of 2(2+2) treats it as the same

            you’re straight up just spouting contradictory nonsense now because you’ve realised your stance doesn’t make any sense, and i am very much here for it
