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…
uhhhh that’s not how everyone does it?
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
Common core math calls that “friendly numbers”.
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
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.”
This has nothing to do with ADHD… mixing up stuff is just confusing people
This has absolutely nothing to do with ADHD
I have no attention span and this is not how I do math.
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.
That’s the smart way to do math. I mean not with such small numbers but you’d do the same thing adding up large numbers, you break down the numbers and rearrange them in a way that’s easier to compute.
Algebra probably feels intuitive to you.
They’re also trying to teach that in math classes (it gets called “new” math) but the boomers are freaking out because “why can’t they just do normal additions like we used to, this is so complicated”. And the answer to that is, 99% of the time you’ll be doing algebra because we literally all carry a calculator in our pockets and sometimes on our wrists at all times and we never need to just do a long division. And that kind of thinking really makes it easy to break down formulas because your brain thinks in terms of moving stuff around in an equation.

So, as a childless Xennial, I have to ask… is today’s “new math” the same “new math” that people complained about in the 60s?
If so, that’s an awfully long time for something to be shunned as “new.”
we never need to just do a long division.
Truth. I recently got a neuropsych evaluation and part of it was an unexpected (to me) IQ test. And staring me in the face, for the first time in ~30 years, was a few pages of arithmetic problems. Took me a minute to recall how to do decimal multiplication but it did come back to me. Long division? Nope. Had no freaking clue. Given that it was timed I just left blank anything I couldn’t work out in my head. Maybe if I had time for trial and error I could have eventually figured it out. But one thing is for sure… the odds of me ever needing that skill again are fairly low.
isn’t the problem specifically that some people just can’t really do intuitive math for small numbers? like all through school everyone else just breezed through memorizing the multiplication tables and i just sat there manually adding numbers together and felt so fucking stupid and worthless in math class
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.
No, since 6+6=12, then because 7 is one more than 6, 6+7=13
7 + how much is ten? 3
How much is left? 3
Ten plus however much is left = 13Wait I do that kind of math and I am not adhd?
I’m aspergers with adhd, so 🤷
i was gonna say, this is ADHD math? I just thought this was mental math in short lmao.
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.
That’s my strat too. Also confused what this has to do with adhd
But… But… That’s just CORE MATH YOU CAN’T CHANGE MATH! /s
MATH IS MATH
That’s how our math teacher taught us to take shortcuts in elementary school.
7+6=? 7+3+3=? 10+3=? 13=13 (Not ADHD)
6=3+3, 7+3=10, 10+3=13
PS I had to edit this post because of typos.
I calculate percentage like this. If 100% is the value, then I know what 10% is, then1%, so I do increments of both until I get to the correct value.
It may sound stupid,but it does help me get a % fast enough.
Thank you! That’s pretty neat. I tried 27% of 65
I added two 10% increments (6.5+6.5)… but instead of adding 0.65 (1%) seven more times, I added a 5% increment (6.5/2 = 3.25) and then 2 increments of 1%
So 6.5+6.5+3.25+0.65+0.65 = 17.55
I still had to use a calculator to add those weird numbers (and also check my work), but it does seem really practical for easier numbers. I usually need percentages for pricing (i.e. discounts/tipping), and the percentages are normally in increments of 5%, so that’s pretty useful for figuring out a 15% or 75% of something real quick… or at least get me really close (when talking about something like $X.99)
Regardless, I appreciate the head trick!
Edit: I guess I could’ve done 30% and then subtracted 1% twice; but it’s the same issue (of adding weird numbers) with the same outcome anyway. So thanks again!
Another neat trick: X% of Y is equal to Y% of X. That is, in your example, 27% of 65 == 65% of 27. So check and see which combination might provide fewer steps/messy numbers.
13.5 (50% of 27) + 2.7 (10% of 27) + 1.35 (5% of 27) = 17.55
Ahh, that’s a really good point! I forget about the “X% of Y = Y% of X”
Honestly, I normally just use a calculator quick (move the decimal twice, multiply and all that jazz) for weird percentages or I want a precise answer.
But I like knowing different ways of thinking about it because it can become easier than using a calculator (with practice). And it’s fun, cause I’m a bit of a math nerd
Ooh good trick
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.
