    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.

    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.

      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

    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.

    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.

    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.

      Kinda the same.

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

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

      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.
