I wrote a (very long) blog post about those viral math problems and am looking for feedback, especially from people who are not convinced that the problem is ambiguous.

It’s about a 30min read so thank you in advance if you really take the time to read it, but I think it’s worth it if you joined such discussions in the past, but I’m probably biased because I wrote it :)

    Def not a math major (BS/PharmD), but your explanation was like seeing through a visual illusion for the first time! lol

    I was always taught PEMDAS growing up, and that the MD and the AS was read left to right in an equation like above. But stating the division as a fraction completely changes my mind now about how this calculation works. I think what would happen in a calculation I use every day if the former was used.

    Example: Cockcroft-Gault Equation (estimation of renal function)

    (140-age)(kg) / 72(SCr) vs (140-age) X kg ➗72 X SCr

    In the first eq (correct one) an 80yo patient who weighs 65kg and has an SCr ~ 1.5 = 36.11

    In the latter it = 81.25 (waaay too high for an 80yo lol)

    edit: calculation variable
