    There’s no sense in which it does refer to the result you mean.

    “a X b is written ab.” Modern Algebra: Structure And Method, page 36. It’s only a different way of writing the exact same thing.

    Go ahead and try it out and let me know how you go.

    Every textbook ever written disagrees with how you think brackets work, and mathematics has not collapsed in on itself. We’ve seen your Mastodon posts lamenting how ‘university people’ all disagree with what you lie to teenagers about. All of them! Weird, right? What a bizarre coincidence. I’m not sure what would look different if you were just plain full of shit.

    So when you sneer that rules and notation are different, you don’t know what those words mean.

    Or you’re so devoid of internality that when someone says ‘imagine a different notation,’ you literally can’t.

    There’s no pretending, It’s there in the textbooks

    Show me any textbook that gets the answers you insist on. Show me one textbook where a(b+c)2 squares a.

    No you can’t!

    Yes we could, because it’s a theoretical different notation. Mathematics itself does not break down, if you have to put add explicit brackets to 1/(ab).

    Mathematics does break down when you insist a(b)2 gets an a2 term, for certain values of b. It’s why you’ve had to invent exceptions to your made-up bullshit, and pretend 2(8)2 gets different answers when simplified from 2(5+3)2 versus 2(8*1)2.

    ‘If a+b equals b+a, why is 1/a+b different from 1/b+a?’

    ab means a*b.

    That’s why 1/ab=1/(a*b).

    But we could just as easily say 1/ab = (1/a)*b, because that distinction is only convention.

    None of which excuses your horseshit belief that a(b)2 occasionally means (ab)2.

    That’s convention for notation, not a distinction between a*b and ab both being the product of a and b.

    You have to slap 1/ in front of things and pretend that’s the subject, to avoid these textbooks telling you, ab means a*b. They are the same thing. They are one term.
