      Exponents come after brackets, so I’m curious to see how you solve that with your logic lol. It has an obvious correct solution, which is 128, but you need to distribute in the brackets step, which comes before exponents, so let’s see what you do with it lmao.

      • Exponents come after brackets

        That’s right

        so I’m curious to see how you solve that with your logic

        Ummm, you do the brackets and then the exponent. Not sure what you find unclear about that

        It has an obvious correct solution

        The one where you do the brackets before the exponent

        which is 128

        Nope! You can only get that by doing the exponent before the brackets, which is against the order of operations rules. Or did you wrongly add a multiply sign before the brackets - that also yields a different answer

        you need to distribute in the brackets step

        That’s right, so why did you do the exponent first?

        which comes before exponents,

        That’s right. So why did you do the exponent first?

        so let’s see what you do with it

        Brackets before exponents, as already established 🙄

          Ok bro now find an expression solver that verifies your solution. I tried Wolfram Alpha, Google, and others, and they all return 128. So either you’re wrong, or all people who make these tools professionally are wrong. Not trying to be offensive, but I know where I’m putting my money.

          To be clear, the reason you’re wrong is because distribution is not part of the brackets step. Brackets are solved before exponents, resulting in 2(8)². Remove the brackets and then it’s 2*8²

          • I tried Wolfram Alpha, Google, and others, and they all return 128

            Yep, all known to give wrong order of operations answers

            So either you’re wrong

            Well, it’s not me, so…

            all people who make these tools professionally are wrong

            That’s right. Welcome to programmers writing Maths apps without checking that they have their Maths right first. BTW, in some cases it’s as bad as one of their calculators saying 2+3x4=20! 😂

            To be clear, the reason you’re wrong is because distribution is not part of the brackets step

            To be clear, I am correct, because Distribution is part of the Brackets step, as we have already established…

            Brackets are solved before exponents,

            Yes

            resulting in 2(8)²

            No, you haven’t finished solving the Brackets yet, which you must do before proceeding…

            Remove the brackets and then it’s 2*8²

            Nope! We have already established that you cannot remove the brackets if you haven’t Distributed yet

            So what we actually get is…

            2(8)²=(2x8)²=16²

            and now that I have removed the Brackets, I can now do the exponent,

            16²=256

            Welcome to you finding the answer to 2x(3+5)² - where the 2 is separate to the brackets, separated from them by the multiply sign - rather than 2(3+5)², which has no multiply sign, and therefore the 2 must be Distributed

              Lmao citing yourself and assuming you’re correct and smarter than everyone who programs solvers, even those who are known to be respectable and used extensively in academia. Nothing’s been established cause you’ve cited sources that don’t support your argument, and repeating them again and again won’t make it different. Good day bro, continuing this is useless.

              • Lmao citing yourself

                Nope! I cite Maths textbooks here, here, here, here, here, here, here, a calculator here, need I go on? 🙄 There’s plenty more of them

                assuming you’re correct and smarter than everyone who programs solvers,

                That’s hilarious that you think random programmers know more about Maths than a Maths professional 😂

                even those who are known to be respectable and used extensively in academia

                As I already stated, everyone knows the complete opposite of that about them. It’s hilarious that you’re trying to prop up places that give both right and wrong answers to the exact same expression as somehow being “respectable”. 😂 And you’ll see at the end of that thread - if you decide to read it this time - the poof that academia does not use it (because they know it spits out random answers)

                Nothing’s been established cause you’ve cited sources that don’t support your argument

                BWAHAHAHAAH! Like?? 😂

                repeating them again and again won’t make it different.

                That’s right, the Maths textbooks are still as correct about it as the first time I cited them.

                continuing this is useless

                Well it is when you don’t bother reading the links, which you’ve just proven is the case

                  I’ve read everything you’ve posted, but the problem is you’re interpreting the texts in such a way that they support your flawed argument, conveniently ignoring what they’re actually saying, such as “if” statements.

                  Even this textbook that you yourself posted goes against what you’re saying if you just bother to look at it outside of your tunnel vision:

                  Notice something?

                  • I’ve read everything you’ve posted

                    You’ve read every textbook, and looked at the calculator answer? Yeah nah, you clearly haven’t.

                    you’re interpreting the texts in such a way that they support your flawed argument

                    Says person who can’t come up with any textbooks that support their argument. 😂 BTW if you had looked at the calculator, you would’ve seen it does it exactly as I have described - 6/2(1+2)=6/2(3)=6/(2x3)=6/6=1, not, you know, 6/2(1+2)=3(3)=9, which is your flawed argument

                    conveniently ignoring what they’re actually saying, such as “if” statements

                    Says person ignoring this “if” statement which says you literally must distribute if you want to remove the brackets.

                    Even this textbook that you yourself posted goes against what you’re saying

                    No it doesn’t! 😂

                    Notice something?

                    Yes, you ignored the Distribution in the last step 😂 I have no idea what you think is significant about the first 2 steps, other than you were trying to draw attention away from the Distribution in the last step

                    Here’s another one (different authors) that does the same thing, which you would’ve seen if you had actually read all the textbooks I posted, but they explicitly spell out what they’re doing as they’re doing it…

              • Like how the 5 in the first image isn’t?

                BWAHAHAHAHAHA! And how exactly do you think they got from 5(17) to 85 without distributing?? 🤣 Spoiler alert, this is what they actually did…

                5(17)=(5x17)=85

                They do that throughout the book, because they think it’s so trivial to get from 5(17) to 85, that if you don’t know how to do it without writing (5x17) first, then you have deeper problems than just not knowing how to Distribute 😂
