Common core made an effort to teach kids to think about numbers this way and people flipped the fuck out because that wasn't how they were taught. Still mad about that.
There's ~~people~~aliens who would add 9+7 instead of 10+6 or 8+8 in their heads?
I do, because 9 plus anything is just a 1 in front of the other digit minus 1.
Weirdly enough, I just thought about using the methods here for the first time in my life earlier today. Weird.
My brain did something similar, but maybe weirder.
7 + 3 + 6, rather than 9 + 1 + 6.
