PittTheElder posted:The ambiguity arises because mathematics doesn't specify an explicit preference to multiplication and division operations, and because they used obelus (÷) notation in a deliberate attempt to make it unclear which portions of the equation are in the numerator and denominator. Added to this is that different areas of the world use conflicting acronyms to teach order of operations, so that people on the 'gram can have lots of boring arguments about which is 'correct'. So the answer is "probably 1, but maybe 16; either way you should get better at writing equations."

No he doesn't:quote:Now realize, following Aunt Sally is purely a matter of convention. In that sense, PEMDAS is arbitrary. Furthermore, in my experience as a mathematician, expressions like 8÷2×4 look absurdly contrived. No professional mathematician would ever write something so obviously ambiguous. We would insert parentheses to indicate our meaning and to signal whether the division should be carried out first, or the multiplication.

PittTheElder posted:No he doesn't: A bit earlier: quote:When confronted with 8 ÷ 2(2+2), everyone on Twitter agreed that the 2+2 in parentheses should be evaluated first. That’s what our teachers told us: Deal with whatever is in parentheses first. Of course, 2+2 = 4. So the question boils down to 8÷2×4. I mean yes, it's a convention and arbitrary, but it's not something where there are two different conventions.
