Edit: it appears that this is not exclusive to ADHD.

Posting this meme stemmed from my own efforts to explain my thought process when doing math and how it is similar to other people with ADHD doing math, while being different from every neurotypical person I’d talked to on the same subject.

While I didn’t make the meme itself, instead finding it in my saves and wanting to share, I did accidentally spread misinformation that I had only backed up with personal anecdotal evidence.

I’ll leave this up just so people can see the explanation below but this appears to not be ADHD related and just due to different people doing math in their heads differently…

    This has nothing to do with ADHD… mixing up stuff is just confusing people

      Nah, I’m down with the 9s. 9+6 is 15 so it must be 13

        Nah that’s 8+8=16 so 16 -2 is 14. 14 -1 is 13, so 13. or as my maths teacher said. Wat? 1 point, negative 0.5 for incorrect formula 0.5 total. Even though it always worked!

        Edit: Hell other ways to work it out. 7+7=13 logically vs my calculator so 5+5+5 = 15. 15 is incorrect why? because +5 is +2 more than necessary so 7+7 must equal 5+5+3 which = 13 or as my mental maths exam told me Fuck you! You Fail! Can’t do maths in 10 seconds then you are either retarded or have another mental issue, to the stupid class you go! (It wasn’t stupid class if those students got the support they needed they would have excelled!) (You had to pretend to be “normal” to make “academic progress”))

        3+3 =6. 6 < 7 so 3+3+3+3 = 12 but 6<7 so 12+0.5+0.5 =13

      7+6

      You need 3 to get to 10. 3 left over. 10+3=13.

      I’d split up the 6 into (3,3) in my head

      Same thing as 7+3+3

      It is. Some people find more common numbers easier to add, then just figure out the difference. People in this community love to call totally normal stuff “adhd logic.”

    No, since 6+6=12, then because 7 is one more than 6, 6+7=13

    I’m sorry, but this is a silly statement. This is by no means an ADHD thing. It’s a pattern understanding or logic

    I’m trying to teach my kid this. Not to use this specific method for addition, but recognize and understand patterns in math.

      What most people misunderstand about mental illness diagnoses is that most people have most of these symptoms. It’s only when these symptoms overlap and disrupt your ability to *healthily function as an individual that they require a diagnosis and medication/therapy.

      Edit: Added healthily as that’s the real distinction.

    7 is closer to 10 than 6 so we consider that 7 is really just a 10 with a size-3 hole in it and we fill that hole with 3 from the 6 giving a 10 with 3 left over which make 13.

    Also not an ADHD thing.

    Interesting, I make sets of 10. When I see 7 and 6, half of the 6 moves over to make 10 + 3. I say “moves over” because it feels like dividing tokens into sets in my head.

      Elementary school had us using tokens for math constantly and it made it way harder for me. Especially cause ‘showing our work’ meant basically drawing the lil tokens on paper that were either black or white I think black represented a minus and white represented a plus (on paper, they were red and yellow irl). So I ended out doing the equation different and then reverse engineering the method they wanted from me.

    That’s just called using heuristics, friend, though if ADHD impeded their progress in math, maybe ADHD people rely more on heuristics than neurotypicals do.

    i was gonna say, this is ADHD math? I just thought this was mental math in short lmao.

    This is how it is supposed to be taught. Common core has this exact quality of numbers explicitly shield or in primary school curriculum. Numbers are not static objects but the composite of infinite functions that can be used to determine the value in whatever base number system you want. Next time someone says school didn’t teach math remind them that the US is something like 30th in the world at math and when the department of education tried to do something about it parents said it was too hard to understand and we just kept falling backwards.

      I agree that this is how it should be taught. I wasn’t taught it until high school. And even then it was by a university student who came to our physics class to talk to us about the kinds of things we could expect in university. :p

      I’m in Canada btw.

    That’s how our math teacher taught us to take shortcuts in elementary school.
