  • Now isn’t the time to start being pedantic about rules.

    edit: the prompt says “Circle the smallest number” and not “Circle the smallest number that appears below”. What is the smallest number? 0 (at least by magnitude, negative numbers are just bigger numbers in the negative direction). So the prompt effectively says “Circle the zero”

    If we’re going to work off the “that appears below” assumption. then the smallest number is “1” and not 1, 2, and 3. So circling all 3 is incorrect.

    If we’re going to work off “that appears below, not including the categories” then the number to circle is 15 specifically. Not the “2.” in front of it.

    And if there is a “circle the category indicator number for the category that includes the smallest number below” implication, then it’s truly just a bad question. Make it clear what you want.







  • And yet Maths textbooks do! 😂

    “No one” in this context meant “no one who actually does maths professionally.”

    In a Maths textbook

    Right, and I have decades of maths experience outside of textbooks. So it’s probably been 20 years since I had a meaningful interaction with the × multiplication symbol.

    You don’t know that the obelus means divide??

    I clearly know what the symbol means, I demonstrated a use of it. But again, haven’t had a meaningful interaction with the symbol in 20 years, and yet I deal with / for division daily.

    When I see 1+½ i can instantly say “one and a half”, but when I see 1 + 1 ÷ 2 i actually have to pause for a moment to think about order of operations. Same with 1+2x vs 1 + 2 × x … one I recognize the structure of the problem immediately, and one feels foreign.

    The point is that people who do maths for a living, and are probably above average in maths, tend to write things differently than people who are stopped their maths education in high school (or lower), and these types of memes are designed around making people who know high school maths feel smart. People who actually know maths don’t need memes to justify being better at maths than the rest of the public.


  • Most actual math people never have to think about pemdas here because no one would ever write a problem like this. The trick here is “when was the last time I saw an X to mean multiplication” so I would already be off about it

    1 + 1/2 in my brain is clearly 1.5, but 1+1÷2 doesn’t even register in my brain properly.
