    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


  • So unless you live in an area with fiber, asymmetrical speeds are pretty typical… I’m not sure if it is because it’s all coax so there are infrastructure limitations? But it’s actually gotten faster because 6 months ago my upload was only 30 mbit/s.

    Once fiber is in my area I’ll switch to that, but symmetrical will add more cost…but of course it will lol
