The Chinese student put the same answer on the second and third equation,which is wrong because on the second equation the answer is 8 and not 6. Overall the American student tackle it in an understanding way even though it took time but it’s worth it which shows that she knows the basics of solving problems like this.
an easier way to calculate this would’ve been to double the 14 and half the 12.. 6x28 is the same as 12x14 then you can do the mental calculation for 6x28 much easier and quicker. 6x8 = 48, carry the 4 and 2x6 = 12+4 = 16 bring the number down and you have 168

Long multiplication is the quickest on paper imo. The "American" method seems pretty tedious but does work for any combination of numbers. However, the trick the Chinese student displayed only applies to two digit by two digit numbers and also she did it backwards. I would've started from least significant digits for the case you end up with carry over digits.
As a chinese I can relate to this when I was in school in china the math was hard for me to understand but now I’m in America and now is way easier to understand.
we are taught this in american schools tho (well i'm british, idk why i'm saying this), it's just in an algebraic context (x+a)(x+b)= x^2 + ax + bx + ab
bro this method isnt any gimmick or anything. Its just a different way to visualize multiplication thats kind of confusing to many people. Guys its not a gimmick, the Chinese student just visualizes it better than you!
I learned it as 12 * 14 ____________ 48 + 120 ____________ 168 But the last time i used it was in like 4th or 5th grade maybe bc we had to show the work Now i just do it in my head as 12*10 + 12*4
Whats thepoint 12 *14 4 x 1 = 4, 4 x 2 = 8 so 1st line is 84, 1 x 2 = 2, 1*1 = 1 put 0 in the and then put 21 and + all of them,so 48 +120 168. This took me 4 seconds to answer with a paper, but typing was like 10 mins
14x14=196 1x1=1 4+4=8 4x4=16 You have to add the 8 from 4+4 to the 1 from 4x4. It works like that cause in this case both the 1 and the 8 (really an 80) is a ten. When you add those you get 90, then you have the 6 leftover and when you add it all together you get 196

😂
Let’s most of all not bother to notice that the “2”s and “4”s are written the same. Common sense
Bruh what is this nonsense??? This dumb trick the Chinese student used doesn’t even work on all kinds of problems.
actually, no one use this way just
14
x12
---
28
140
---
168
They are trying to dumb down Americans even more than has already been done.
they didn't show the rules for it, it only works for some types of problemss
Me - using calculator and finding answer before you guys do 👁️👄👁️
european students:
10 x 14 = 140
+ (2 x 14 =) 28
= 168
way more simple, way faster 😂
America: So everyone understood right? Great!
Asia: JUST MEMORIZE EVERY MULTIPLICATION!!!!!!
Long multiplication is the quickest on paper imo. The "American" method seems pretty tedious but does work for any combination of numbers. However, the trick the Chinese student displayed only applies to two digit by two digit numbers and also she did it backwards. I would've started from least significant digits for the case you end up with carry over digits.
American friend: yo what are you doing?
Chineese friend: studying maths bro 😮
As a chinese I can relate to this when I was in school in china the math was hard for me to understand but now I’m in America and now is way easier to understand.
Tell me the Chinese method for finding 12*534
we are taught this in american schools tho (well i'm british, idk why i'm saying this), it's just in an algebraic context (x+a)(x+b)= x^2 + ax + bx + ab
I do my math like I'm Chinese but I'm American 🤔
Full Version
12x14
(10+2)(10+4)
10x10 + 10x4 + 10x2 + 2x4
100 + 60 + 8
168
(Note : The Right Kid just Simplify those Number)

Like if you 👍🏻 agree
Amazing talga! ang dali-daling strategy.
I like using squares as waypoints, so e.g. 12*14=144+24=168
bro this method isnt any gimmick or anything. Its just a different way to visualize multiplication thats kind of confusing to many people. Guys its not a gimmick, the Chinese student just visualizes it better than you!
the second step is actually part of Vedic maths (Ancient mathematics followed in India)
Indian Math: Direct answer. Kyunki hum tables yaad karte hai😜😤💯
Now that's emotional damage. Math is about understanding and breaking a bigger problem into smaller version and then solving it logically.
Fun fact: if you haven’t seen before, mental arithmetic is actually faster than using a calculator
I learned it as
12
* 14
____________
48
+ 120
____________
168
But the last time i used it was in like 4th or 5th grade maybe bc we had to show the work
Now i just do it in my head as
12*10 + 12*4
Japanese: we wanna make everyone understand!
Indian: JUST MEMORIZE IT
This Chinese student used common core method (but in a creative way, I think): 12x14=(10+2)x(10+4)=10x10+(2+4)x10+2x4=168
Both are complicated and takes time to memorize, here’s how i do it
(12 x 10) + (12 x 4)
120 + 48 = 168
🤷🏽♂️
Me: Does this method
Teacher: With solution!
Me: Well shit
If we do a math question like Chinese students means direct so our teacher will also give the direct number of only one step 😆😆😂
My American Math teachers in the 90's did NOT show us this method.....
I would probably do most of it in my head but probably mostly the same method. 12x10=120 12x4=48 120+48=168 (I’m American if you care)
Those kid solving this silly question while my mind-
12×14
12×10=120
12×4=48
120+48= 168
If you think it is long it is so easy
another method:
14x1=14
Skip to 14×10 cuase its more than 10 the times you are going to multiply.
14x10=140
14x11=154
14x12 =168
EASY
Whats thepoint
12
*14 4 x 1 = 4, 4 x 2 = 8 so 1st line is 84, 1 x 2 = 2, 1*1 = 1 put 0 in the and then put 21 and + all of them,so
48
+120
168. This took me 4 seconds to answer with a paper, but typing was like 10 mins
Omg i was looking for this, i'm from the west and I learned this which is fast and I can do it in my head.
To be fair the American student wrote it in the longest way possible
Chinese students are smarter.
American system is less complicated.
10x14=140
2×14=28
140+28=168
It was written in a difficult way on purpose, both girls are chinese btw.
America:your in 6th grade learn algebra NOW
China: ok your in 6th grade let's do some basic math
Me:
MIND CALCULATOR
How would 14 times 14 work???
14x14=196
1x1=1
4+4=8
4x4=16
You have to add the 8 from 4+4 to the 1 from 4x4. It works like that cause in this case both the 1 and the 8 (really an 80) is a ten. When you add those you get 90, then you have the 6 leftover and when you add it all together you get 196
In this type of sum indian only see the and answer them😂😂😂😂
Philippines: hmm just simple brain can answer only 1 sec
Tbh I just did it in my brain
2 years working in a grocery store just does that
America and Chinese use almost the same math equations it’s just that they have a much fast speed in learning
Bruv I can’t work that out in my head
It’s literally basic multiplication
I've never done that in American math. 😂 That Chinese method looks interesting though.
