The biggest I’ve seen in a published source in the wild is an 80-fold error in a reported distance, which I think came from a series of at least three unit conversions and area/length misinterpretations.

    Did you not notice the unit modifier in the my second phrase???

    Let me spell it out for you.

    3 (three) ’ (feet) ^2 (squared)

    You’d have me repeating myself like a monkey, which is, NINE.

    3 (three) sq (square) ft (feet) is THREE.

    but I suspect you’ll disagree at at this point I’ll move on, my only sadness is there was a person out there who agreed with your original argument that they were the same.

            Okay,

            There’s this thing called the order of operations

            And seeing as how you don’t know about it, it makes sense that you won’t know the difference between square miles and miles squared.

            Please check out a junior high school math text book before bothering to argue on the Internet.

            Edit i see where you’ve made the mistake,

            If it’s (3+4)^2 then you’ve failed to combine like units, something they teach you about in kindergarten.

              No, I was clearly thinking of parentheses when I wrote it, so you should have said them when you said it.

              Take your meds, Donnie.
