You may ask, "Well what about something like 7+16??" or for anything that doesn't have a 9 in the ones digit. And to answer, I'd take the one with the ones digit that's closer to 10, then just keep moving 1 until it IS 10. 7+3+=10, 16-3+13. Then I'd add 10 and 13 for 23.
It's wacky, and not at all fast. But it's just how i comprehend it. It's the way my brain wants to do it.
I don’t think they’re purposefully using tricks to get the answer. Their brain just can’t stay on the standard track so it gets to the answer the best way it can
I have had math awards given to me my entire life, with 99% in my past 3 math classes in high school on top of that. Yet still, I process 9 + 7 as 10 + 6, or something like 17 + 8 as 20 + 5. It's most definitely not a trick that I need, it's just how my brain computes things. (Also, I don't even have ADHD that I know of, I just relate to this post)
Interestingly, the common core math program they got kids on incorporates things like this. Among other ideas that seem way to complicated. This trick was actually the notion that helped me understand wtf they were doing because unless you consciously acknowledge that you are doing these kinds of things CC makes no bit of sense. I had a lot of trouble helping a fifth grader with homework because I had no idea what they were doing. That said, I got points off all the time in school for making up my formulas. In retrospect, I should have gotten extra points!! It worked! I got the right answer!!
