I gotta say, even though I already basically understood what the long multiplication was doing, and basically do the same thing whenever I do mental multiplication, seeing it laid out like this gives me renewed respect for it. It's really an ingenious little algorithm for quickly computing a product by hand.
This video was so helpful. I had to learn this to help my daughter with her homework. Other videos did not help, we kept getting wrong answers....we got 8/8!!! Thank you!
That's pretty amazing. I wish we would have learned math this way when I was a kid, I know I would've picked up math more intuitively.
me too
We
Thank you it worked for homework for face to face school⚡️
Saved me from failing a test
Thanks 🙂🙂
I’m doing this for school work but it’s covid 19 anyone else
Same onlin school sucks
👍 yep
Rockskull_ :D Yes I am lol
I am
Yea i hate this lesson
aye needed it for school🙃🙃🙃😃😃😃
thanks! it was really helpful for me to understand 2 digit by 2 digit!!!
Anyone make a "multiplication with the area model" t-shirt? I think the visual of connecting this to the standard algorithm is super compelling, especially with color coding for each of the partial products. I'd be stoked to wear that on my back!
nice 😍
this is a very helpful video that helps for studying
The graph paper explanation is a good tool to understand what a number represents as far as One's, Ten's, Hundred's, etc however, this should of already been taught when teach basic Addition and Subtraction. Once again educators are trying to put the cart before the horse.
My math cllub teach uses your videvs for math
It makes much more sense ❤
...and that just added two extra steps to the math problem.
Mike Rushing I don't get your point. If the point of math class was to churn out answers, we should all just take calculator (phone) class and be done with it. This is a method of teaching an abstract CONCEPT visually. 4 x 5 = 20 can be easily represented and taught visually, and then the method can be scaled up too.
Once you understand that a multiplication problem is just an area of sections or a sum of sums, you can then translate real-world words and questions into arithmetic problems - because you understand the relationship between numbers and meaning.
think it very helpfull
Helpful for understanding
Excellent... Crystal clear concepts :D
Great! Thank you again.
all other videos about this say that this for 3rd and 4th graders, i'm struggling with this and i graduated high school last week
Same here my 9 year old has to deal with this, lol
Thanks needed it for school😀😀😀😀😀
same!
Thanks bro!!
I do it a little different so can u try 2 do other ways pleasezzzzzz!!! The good thing that you are the only one I trust with my homework!!
If you're looking for the traditional, standard method that everywhere else in the world is being taught how to do, then he starts that at 6:07.
DanceFiendStrapS this isn't just an American thing, you know? it's for anyone. just another way of looking at it.. helps the brain =)
Thank you very much that helps
my teacher is right about you
Same
Thank you for this and who is watching this in 2020 because I am but don't worry i hate it T^T.
Yep
What program is that that your using
Khan academy
Thank
This getting 400,000 views cause of COVID 19😅😂
yep
my teacher wanted me to watch this even tho i learned this is 2nd grade
Same
Why is that Square bigger
Me acting like I am watching the video but keeps repeating it and reading chat ;-;
We probably all doing this)
Who are seeing this video in lock down time give one like
Guitar tuning
:)
ce

Hi
complex
Who is where for school in 2021
pooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooop
Math 😔
But resepct
You
this is making things way more complicated than they need to be. 16 x 30 you can do in your head. minus 16 x 3 and you get the answer.
areas of sections. math doesnt need a backstory?
I did not know that second way. I know I'm dumb.
:D
Who in 2021 in school
me
Here
2020 school video check (┬┬﹏┬┬)
for what reason is this video 8 mins long.
ASMR????
is it just me or was he farting while counting to 20 💀💀💀
STOP WORRYING ABOUT THE COLORS!!
i'm the 100th comment
hi
sup bro
Anyone from school just me ok
Education levels in America have not gotten better since common core, in fact it has gotten worse! People are now asking "where to now" with regard to teaching methods, because if you do a cursory search for "common core review" you'll notice it has in fact failed. How do you justify using common core when the results are terrible? You'll be laughed out of any STEM field, I'm sorry, but this is a waste of time.
Wtf what about fractions da heck
Boi
poooooooooooooooooop
This is the stupidest way of doing multiplication. I hope Common Core stays in America.
Nah, this is far more intuitive than the standard algorithm I learned in gradeschool.
shut up
This is stupid , this would confuse any kid
Like you
U dumb bruh or bro or dude
