  Please find a calculator that gives a result different to 128 for the expression 2(3+5)². Should be easy, no?

  Please find a Maths textbook that backs that up as being the correct answer. i.e. Exponents before Brackets. Should be easy, no? 🤣

    Nobody has argued exponents should go before brackets.

    I’m saying distribution being mandatory is an invented rule from your part.

    No wonder you can’t produce such a simple request. I thought you had calculators that work “correctly”?

      You did! 😂 You said 2(3+5)²=2(8)²=2(64), which is doing the Exponent when there are still unsolved Brackets 😂

      You still haven’t explained how it’s in 19th Century textbooks if I “made it up”! 😂

      If you don’t remember Roman Numerals either, that’s 1898

      says person who still hasn’t produced a single textbook that supports anything that they say, and it’s such a simple request 😂

        Unsolved brackets

        Solving brackets does not include forced distribution. Juxtaposition means multiplication, and as such, 2(3+5)² is the same as 2*(3+5)², so once the brackets result in 8, they’re solved.

        Distribution needs to happen if you want to remove the brackets while there are still multiple terms inside, but it’s still a part of the multiplication. You can’t do it if there is an exponent, which has higher priority.

        Your whole argument hangs on the misinterpretation of textbooks. This is what it feels like to argue against Bible fanatics lmao.

        Tell you what, provide me a solver that says 2(3+5)² is 256 and you’ve won, it’s so easy no?
