I would prioritise making a perfect 10 out of that 6, and then handling the remainder.
7 + 6 3 + 4 + 6 3 + 10 13Also, how is this relevant to ADHD?
Is this mostly a ADHD thing? They tried to make me learn times tables at school but that never stuck. Recently had to solve a problem with a CRC and part of that was manually calculating a long division in binary. At some point realised I didn’t even know how to do that in decimal so wound the clock back 35 years and learnt it from scratch. Badda bing badda boom, working CRC 🤓
Is this not just how people do simple math? Why the hell else did they make us just memorize multiplication tables?
In elementary school my son would not memorize addition and multiplication and just use strategies like this.
That became a problem later on as we just can handle a finite number of intermediary results in our brain, so just memorizing the tables reduces a lot of mental load for calculation in your brain.
Another thing that helped him a lot was just writing down intermediaries on a piece of paper.
Btw it was a bit similar for me, I just got the table memorized perfectly and got faster doing simple calculations in my mind than using a calculator when I was training the multiplication and addition tables with my son.
three of the six falls into the gap between the 7 and 10, leaving 3 sticking out the top = 13.
I have no idea if this is normal or not
I think I do something similar. Basically.10-7=3, 3+3=6 so 7+3+3=13 or simplified 7+6=13. Or like the above with 7+7=14 therefore 7+6=13
That’s exactly how I do it!
i actually do do this. also sometimes 7 + 6 = 7 + (3 + 3) = (7 + 3) + 3 = 10 + 3 = 13!
btw: i studied math.
This is part of common core math
Making Tens (and Hundreds): Composing and decomposing: Students learn to break down numbers to make friendly numbers like 10 or 100, which are easier to add. Example: To add 8 + 5, they might see that 8 needs 2 to make 10. They could take 2 from the 5, leaving 3. Then, they add 8 + 2 = 10, and 10 + 3 = 13.
They are teaching new students this
Can we stop making every little thing about ADHD? This is just a common way to do arithmetic
Normal people: breathing
Me: breathing in ADHD
I don’t think OP has a relevant experience, and it shows with these dumb memes.

This is the exact opposite experience I’ve heard from 90% of my adhd peeps. Cosplay shit.
Came to the comments for this, always done it this way!
Adding up to 10, like the other comment explains, is the common way. Using 14 as intermediate step suggests a different way of thinking. OP could be on to something if that’s normal to you.
7 + 6 = 10 + 3 = 13
Some people have 7+6 = 13 memorized.
Some do 1+6+6 = 1+12 = 13.
Some use offsets from 5, like 5+1+5+2 = 2*5 + 3 = 13
Hell I’m sure somebody did it like 10 - 4 + 10 - 3 = 20 - 7 = 10 + 10 - 7 = 10 + 3 = 13
Now determine the correlation between the various methods and adhd. My guess is that people with adhd are more likely to use the more exotic methods.
Your guess is scientifically worthless. As any other guess, for that matter.
Indeed. The important part are the experiments to determine the correlations. Without those every opinion about OP’s hypothesis in this post is as useless as my guess.
Yeah, kinda annoying
Btw this might break rule 1, sincerely idk
I usually do that approach with multiplication of big numbers and square root calculation. Usually make it at most 10% error, which I consider quite a win :)
It’s just a thing people do, has nothing to do with adhd
I would actually step to 10 first by going (7+3)+(6-3)
Steal some from the 6 to make the 7 round up to 10, then ad the remainder to 10.
Get out of my head, lol. I do this as well.
Stop giving away our secrets…smh
I don’t think this has anything to do with ADHD, it’s just a little shortcut you can use when doing math in your head. I was taught techniques like this in school when we learnt addition and subtraction etc.
It’s also a good way to double check your answers. If you can reach to the same conclusion through different processes, then it’s probably the right answer.
This has nothing to do with ADHD.
Uhm aren’t all people counting like that?
Yeah
Well I suppose some might count by adding 1s or 2s but that looks more ADHD-like than the method we’re talking about here.
everything calculated in my head is just various examples of this daisy chained together
This is just what’s called the “common core method”. It’s now the preferred method of teaching math in many Western countries.
idiology! they’re indoctrinating our children with this woke bullshit now. they’re trying to make us see the “common core” in things. What’s next, they’re gonna tell us that mexicans are people too?
Isn’t this how they teach math now?
I’m 40 years old, and that’s how I was taught. We were quizzed up to 12x12, and that’s way too many products to handle with just rote memorization.
Which to me says that the key takeaway is we were always the smarter ones 🤷♂️
