The new math and old math versions of doing things in that video are actually not nearly as different as the notation would lead you to believe

In the first method you're basically just counting backward from 43

In the second version you're counting forward from 13

I'm not a child psychologist or an education expert so I'm not gonna pretend to know better but as a layman I have a hard time seeing why one method is superior to the other

To be fair they don't teach kids some of the more asinine mathematical functions that can be easily done by a calculator. Because, probably for most people, they do just need to know how to use those functions in larger systems.

All my students like to gripe about how much they hate literature class

I tried to convince them that that's an incredibly important subject because it teaches you about subtext, and how to process and contextualize language beyond its surface meaning, which is a crucially important skill when living in a society full of advertising, propaganda, and doublespeak

They were not interested and I probably should've just told them that they won't get a good job if they can't write a good cover letter

The biggest jump for me in arithmetic was learning how to multiply two numbers with more than one digit each

And even when I got through the mechanics of it it was only years later that I realized that like, you solve 27 x 42 by breaking it out into (27 x 2) + 10(27 x 4)

the fuck is this!

just replace the logic centres of the human brain with a quantum processor and let the singularity take us already.

If I recall correctly, quantum processors are actually way worse at standard logical operations than a traditional processor and/or the human brain. They're very, very good at certain types of complex problems in which many possible solutions are tested at once, but for step-by-step stuff they're woefully inefficient.

In 12th grade calc I sat next to my lifelong crush every day but she started dating another guy and I couldn't deal because it was our last year and there would never be a chance for us again which at the time seemed terribly important

I got so bitter and withdrawn over it that one day she stopped sitting next to me

So if you have

27 x 42

If you learned it the way I learned it, then first you just do 27 x 2 (the first parenthetical up there):

27 x 42
54

(and if you can't just do 27 x 2 off the top of your head you can break it down to (20 x 2) + (7 x 2) or even further to (10 x 2 x 2) + (7 x2))

and then you put a 0 down (that's where the 10 comes in):

27 x 42
54
0

and then you ignore the 2 and just do 4 x 27 (the second parenthetical, which is being multiplied by 10 because of that 0):

27 x 42
54
1080

and then you add them together (the plus sign in that expression!)

27 x 42
54 + 1080
1134

For some reason, I cannot shake that fucking number.

It's 56. I cannot shake that 7 times 8 is 56. IT IS SEARED INTO MY SKULL

Munkus i think i need you to teach me how to common core.

I was in AP math early one, stuff happened i flunked the class, but so did everyone else.

I ended up taking a algebra classs and afterwards my teacher wanted to know why i wasnt in AP, to which i had to give him the back ground.

He recommended me to take pre-calculus, but my student adviser looked at my academic history and said nope, you are taking math and models so you can pass high school. i insisted i wanted to take pre-cal, she still shot me down.

So when i see the common core vid i was LOST, i thought it looked stupid.

But ... its not? If it isnt i need someone to explain to me, show me why its not. I dont want to be ignorant of why it is a good thing.

AP math isn't a thing. AP Calculus?

Just chatted with my friend on hangouts, we are pretty sure it was honors geometry, he failed it as did i and the rest of the class.

Might have had something to do with this whole math concept thing.

So yea... I suddenly feel mathematically inadequite

Yeah, you can't take pre-cal without passing geometry.

And having a better understanding of addition/subtraction might have helped you along with an honors level geometry! I dunno, my geometry teachers were shitty so I was self taught so I don't remember anything!

I mean I know you did it but would it not have possibly been even faster to write it by hand and then take a picture of it and then upload it to imgur and then share the link here than to go through the trouble of trying to make it look right

I got put in Senior math during my senior year because about 3 weeks in the teacher realized I was the only senior in a class of Juniors who were taking a class to get them ready for AP-Calculus (which has the highest failure rate in AP courses).

This was because I took Algebra 2/Trig instead of doing Algebra 2 and then Trig because I was trying to take an accelerated course, despite missing a semester due to my colon surgery. My freshman year, my parent made me take Algebra because they didn't think I was ready for Geometry. Easy 100 I every made...and only one in high school, tbh. But because of that clusterfuck, I went from the hardest math classes to...

...basic GED arithmatic. And since the teacher knew where I was from, and that I was super sick, she let me sleep during class in the infirmary. And because I was sick, they let me drop out of the HELL that was AP Lit (we had a horrible fucking teacher who couldn't teach roadkill) so I was dropped into Myth and Legend, the equivalent of the Senior remedial English since I had already taken the previous AP course.

Considering Economics was about as hard to me as walking for some reason (I would never know why) AP biology was two periods and the AP test was so stupidly easy you didn't have to stupid for it, the hardest class of my senior year was Spanish. And I suck at foreign languages.

Did I mention that I lent my notes to my in depth essay on Dante's Inferno to my friend's then girlfriend, which she proceeded to lose and, what she didn't lose, she tried to copy wholesale. But since the teacher knew me and knew the circumstances, I got an A while the girlfriend failed. It also had something to do with the GF skipping once a week because of 'migraines' to go hang out at the Waffle House with her buddies who also weren't going to graduate.

It was in comparison to the patently awful suggestion of, "Fuck math, teach 'em how to use a calculator"

easiest breakdown of individual sums for me to do in my head

But you could break it down further to make the sums even easier and countable by hand

this isn't on the basis of any mathematical knowledge mind just how I'd do it

Funnily enough I dropped maths at 16 and now ten years later I do loads off maths at work, even if it is really just lots of operations essentially
