I tried to explain ADHD math to someone and they didn't understand at all

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?

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

BirdyBoogleBop , (edited )

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

Sludgeyy ,

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”.

TheFriar ,

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.”

KillingTimeItself ,

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

These ADHD memes hitting a little too hard

Martineski ,

This specific meme is bs and has nothing to do with ADHD.

Well I guess that explains it lol

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.

MrShankles ,

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!

griefreeze ,

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

MrShankles ,

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

Feathercrown ,

Ooh good trick

If you know those five intuitively, adding and subtracting become automatic even with adhd.

1 + 9 = 10

2 + 8 = 10

3 + 7 = 10

4 + 6 = 10

5 + 5 = 10

boredsquirrel ,

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

glimse ,

I try not to be all "that's not ADHD that's just normal" here but yeah this one has nothing to do with ADHD.

boredsquirrel ,

A Therapist told me that there is a lot of nonsense on the web, especially in the AuDHD space, and yeah it tends to go in a "you are a scorpio, you do X" way

I'm a scorpio and I do X all the time

This guy fucks X

One of the worst parts of the latest ADHD wave

And I try not to be all “I’m not ADHD and I do this” on this com, but it’s true.

FiniteBanjo ,

I've got an idea for a meme for you:

ADHD be like:
Man puts on pants

Akasazh ,

The meme has nothing to to with ADHD, however your explication of how it happened does.

You can solve this one with redneck math. You simply flip the numbers in 7+6 upside down, which looks like 4+9, which is clearly 13.

ornery_chemist ,

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.

0ops ,

That's my strat too. Also confused what this has to do with adhd

SendMePhotos ,

But.. But.. That's just CORE MATH YOU CAN'T CHANGE MATH!
/s

Feathercrown ,

MATH IS MATH

AgentGrimstone ,

How I calculate percentages and settle for close enough.

AncientFutureNow ,

get to 10, add what's left.

ealoe ,

This has absolutely nothing to do with ADHD

notanaltaccount ,

I have no attention span and this is not how I do math.

ShortFuse ,

14 & 6 = 6

WolfLink ,

This is a good approach, but for this example I break it up as:

7+6=7+3+3=10+3=13

i_love_FFT ,
@i_love_FFT@lemmy.ml avatar

For me it's:

6 is half a dozen, so 6+6=12, then 7 is 6+1, so 6+7 is 12+1=13

SendMePhotos ,

I did 5 (+2) + 5 (+1) = 10 (+3) = 13
