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...
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.
