Same kind of trick, but for additions involving 7, I subtract 3 from the other number.
wrote last edited by [email protected]Same. I optimize numbers to nicer rounder values and then add on those. 7+6=7+3 to make nice round 10 and then add whatever remains to that, so 10+3=13. I don't know why, it just makes sense.

Isn't this how they teach math now?
Which to me says that the key takeaway is we were always the smarter ones

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.

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.

This is just what's called the "common core method". It's now the preferred method of teaching math in many Western countries.

This has nothing to do with ADHD.

The way i calculate this, is knowing that 7 is 10-3, and 6 is 3+3.
So, 7 + 6 = 10 + 3 = 13

The way I do it:
6+6 = 12 +1 = 13
Dunno how relevant calculating is to ADHD, but it is fun to see how people calculate things in their heads in different ways.

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

Six is two threes and seven plus three is ten so then we have the leftover three and add that to get thirteen.
Also, not everything is ADHD.

Yeah, kinda annoying
Btw this might break rule 1, sincerely idk

Kinda the same.
I need 3 to get to 10 from 7. After that just ad the rest (6-3). Resulting in 13.

I'm pretty sure they just had us brute-force memorize all of the single digit additions and multiplications in grade school. Seemed to work out okay for me.

Came to the comments for this, always done it this way!

generation gap happening here. common core wasn't a thing for a lot of us, it's brand new.
i do math the "common core" way not because it was taught to me but because the old methods didn't work and i had to figure it out on my own.
it may not be strictly "an adhd thing" but society made it so for a time.
