  What’s hard about it is people are fucking stupid.

    No, it’s written poorly to drive engagement. People read left to right and try to do math that way too, but if you want to be mean to people who don’t remember things they learned in elementary school then never applied in real life you write it like this.

    (8-5)5-2

    Far easier for most people, but then you don’t get the arguments…

      I studied physics a bit and order of operations was always clear. Not sure why people are down voting this.

      Yes, thank you! Sure, it’d be great if people remembered arithmetic rules, but just write it better and it won’t matter.

      It’s written the same way literally thousands of math problems in thousands of textbooks have written the same type of math problem for the last 100 years. OP did not write it that way to be “mean.” He wrote it that way because it’s a legit way to write it.

        The operational order is fucked, the way I rewrote is more readable, even if you remember the order. The only reason you’d write the equation like that is to be mean, there’s no reason to write it like that unless you’re trying to trip people up.

  you go the other direction below the equator

    Isn’t the southern hemisphere above the equator if you live there

      depends if you are normal or planar in ENU coordinates

  I fucking suck at math and totally just re-proved it to myself with this problem lmao.

  It didn’t make sense to me to multiply the 3 & the 5 with zero consideration for the “2”. I have ALWAYS struggled with the steps to solve these types of equations.

  So the answer I got was 21. Some of us are just bad with numbers, I s’pose.

    The numbers in the equation and their totals are completely irrelevant to the order you perform the operations.

    I don’t think it’s an issue of “being bad with numbers”, I think the issue is not understanding the logic or being able to understand the bottom up type of thinking or something.

    This is absolutely not a problem of being bad with numbers. That’s like if I had trouble reading a Chinese sentence about gardening and said I’m just bad with plants. My issue is that I’m not familiar with the notation used to explain the concept - not a problem with the concept itself that the notation merely arbitrarily symbolizes.

    Being good or bad at math is not really an inherent thing, aside from some geniuses and some people with disabilities. If you want to be good at math, you can be!

    Its order of operations, to get rid of brackets do the internal, then the 5 tells you there was 5 sets of the amount in brackets. Rather than 2+5 first.

    That’s the answer I arrived at as well, don’t feel so bad. I’m more of a writer than a calculator, though.
