I'm one of those losers that love it.

Not because I initially understood it either.

Fuck that shit. I had trouble showing my "proof" with the old method but I got the right answers and typically got A's in math. I would fail todays math.

Tbh, it makes more sense for mental math.....I mean if you think about how you arrive to answers in your head and less on paper...similar methodology although slightly obsolete. It's less useful, but more comprehensive. It's the same way they teach linear programming, for example, despite being able to rref( plug the shit in your calculator.

They're trying to teach a way to approach numbers in one's own head. You ought not to be slashing and carrying ones over in your head.

I get their reasoning for it. The way we're used to is faster on paper, per se, and best taught afterward.

Doesn't solve our educational problems though...

Each to their own. I used to do long division in my head, on post, to pass the time. I'd just come up with random numbers, like 594,789 divided by 534. After I'd finished I'd do it out on paper to make sure my answer was correct.

I NEVER used the common core math version.

And, my 10-year-old step-son asked me what 32-12 was the other day. I told him to get the answer himself.... that should not be challenging to him. He asked for a pen and a piece of paper, and then was counting things out on his fingers for 5 minutes. Worrying, but he doesn't live with us, and we only see him every two weeks or so, for a couple days.... so there is little we can do.
