'8÷2(2+2)' and the futile wisdom of ISO eighty thousand dash two
once again, the internet has been violently reminded that the true joy of notational standards is that there are so many to choose from! that's right, social media is once again abuzz over an arithmetic expression using the worst symbol, the obelus, '÷'.
neither the specific expression nor the form of it are new. arguments over "8÷2(2+2)" can be found on forum posts at least as early as 2016, and "48÷2(9+3)" was apparently a major controversy in 2011, having its own Know Your Meme page.
