i just don't like how slow it is
A lot of states do have a suggested curriculum that goes along with common core that is, if we're being honest, total ass. Not everyone uses it though.
To be fair I doubt 9/5ths of Americans could do that kind of reverse math.

So right wing backlash against the government doing anything, general distaste for standardized testing, and people not liking changes in teaching math.What Happened to the Common Core?
Just a few years ago, the Common Core state standards were quickly adopted by 45 states and D.C. Now, some states are opting out, and the initiative has come under intense fire from parents, educators, and politicians.www.gse.harvard.edu
No. He's just asking what 30 minus 20 is. But everyone in that movie/future is dumb as bricks that even the one guy from the past (of extremely average intelligence) is the smartest man alive. So the one dude questioning doesn't use the correct terminology of math, well, and even English for that matter. It's really on the nose. Good stuff.
Common core math is just writing out on paper how people actually do math in their heads by grouping the ones, tens, and so on together and doing the math there and bundling it all together for the answer at the end.
Unless I'm misunderstanding you or it's been too long since my course where we made an ALU(Arithmetic Logic Unit?) that's how a computer does it.
I always found it easier to express to people by saying it's how they do math in their head (or with their fingers).
Are you talking about "common core math?" For most arithmetic, it's going to be more steps but way faster to evaluate. It seems slower when students have to write all the steps out (to help them retain the knowledge) but they will be able to much more quickly do even complex arithmetic.
My dad is a special education trainer, meaning he holds seminars and goes to schools helping instruct teachers on special ed techniques. It cracks him up every time "social emotional learning" is used as a scary phrase on Fox News or whatever. Conservatives love scare words so much, they willfully ignore this being standard practice in special education for decades.
