Is This New Math? I Can't Understand Anything! Coli Certs Holders Explain

[Rawtid]

The multiplication I understand. The addition/subtraction is still a little confusing but I get it and I will practice it. My daughter is probably going to learn this new way at some point so it doesn't hurt to know.

that is a stupid ass way to add/subtract.. dont care the logic

It's really not that difficult, just time-consuming.

I can see it being an issue for kids who were like myself in school and preferred to do things in their head rather than show their work.

They'll get the right answer, but since they didn't write down all the steps, they get no credit.......which is stupid.​

My boss was just telling me that this is how her sons are being taught math.
The example she gave me was
Instead of 10 x 6 = 60
They'll have something like (10 x 3) + (5 x 6) = 60

What is new about that?

Where are those numbers coming from?

Y'all just gonna ignore this man's question?

 

[R.E.N. Spells Ren]

you just add random numbers until it equals up to the amount youre subtracting from. all those random numbers you used can just be added up seperately to create the difference between them, which is the answer

While it works with random numbers, the method is not to just use random numbers. It's easier to add 5s, 10s, 100s, etc....the numbers chosen are meant to take advantage of that fact.

This mathematical process is mind blowing, I always wondered how things were calculated when the pyramids were built & what not.

Ummm, they actually left behind their math equations to show us how.......

I just go full when I see someone do some convoluted way to complete a simple math problem.
For a few of the kids I taught, I would ask them to multiply two two-digit numbers, then they'd get to work drawing this bullshyt:

nikka this ain't art class! Do it properly

They could learn all this when they get the basics down and are interested in math theory, but not as an intoduction. It's all about practice and repitition till you find useful patterns, not gimmicks

I think i got it

so 32-12=20

new math is

12+7=19
19+1=20
20+12=32

add 7+1+12 = 20

lol I meant that it looks like a simple algebraic equation but I guess what dude is saying that there are now using longer equations instead of simple math in the first place.

 

[jaydolf spitler]

nah these little kids gotta learn how to carry, no way im confusing small children with this crap

 

[Mensch Fontana]

I think i got it

so 32-12=20

new math is

12+7=19
19+1=20
20+12=32

add 7+1+12 = 20

or or or or or

12+20=32
20+0=20

 

[Mensch Fontana]

use algebra to do simple addition

 

[Supercoolmayo]

I do that kind of stuff in my head

It's werid seeing that stuff on paper
