      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.

    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.

      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.

      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?

    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.

    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.

      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.

              I am wondering about the downvotes. You mean it is offensive to assume that something is different? Thank you for that feedback. I would have never guessed.

                I think people just aren’t on board with your guess, and don’t want to assign every behavior’s root cause to having ADHD

              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.

      Kinda the same.

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

    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.
