It doesn’t work in all situations: 91x51 won’t give u the correct answer using this method. Use your calculator and it is=4641 Using her method you get 45141
@@fargooseisaac4154 The last digit is 1. The middle digit is 9 + 5 = 14. You then put the 4 and carry the 1. The first digit is 9 x 5 = 45. Then add the 1 from earlier, to get 46. Hence, 4641. Why is this? Because what you're _really_ doing is: 1 x 1 = 1 90 + 50 = 140 90 x 50 = 4500 Then what you add them you get 4500 + 140 + 1 = 4641.
Explanation : BRO SIMPLY USE THE CALCULATOR BUT if you wanna do it without calculator here : first take out their both formulas and than divide it by two after dividing add as many number as u can than minus all the numbers you added after that add the number by its value for example 10+10. 20+20. After doing that multiply both numbers with each other and you will get your answer
Title: The Cultural Context of Mathematical Approaches: Why Asian People Tend to Avoid Using "Tricks" in Math Introduction: Mathematics is a universal language, yet its nuances can vary greatly across cultures. One noticeable difference is the approach to problem-solving, particularly regarding the use of "tricks" or shortcuts. In many Western educational systems, students are often encouraged to employ various tricks or shortcuts to solve mathematical problems quickly. However, in Asian cultures, particularly in countries like Japan, South Korea, China, and Singapore, there is a tendency to prioritize understanding and mastering fundamental concepts over relying on tricks. This essay explores the cultural factors that contribute to this phenomenon and the benefits it offers to Asian students. Cultural Emphasis on Mastery: Asian cultures traditionally place a high value on education and academic achievement. However, the focus is not solely on rote memorization or superficial learning but rather on deep understanding and mastery of subjects. In the context of mathematics, this means ensuring that students grasp the fundamental principles and concepts before moving on to more advanced topics. As a result, educators in Asian countries emphasize teaching methods that promote conceptual understanding and problem-solving skills rather than mere memorization of formulas or shortcuts. Emphasis on Process Over Outcome: In many Western educational systems, there is often an emphasis on getting the correct answer quickly, sometimes at the expense of understanding the underlying processes. This can lead to a reliance on tricks or shortcuts that yield the right answer without necessarily understanding why it works. In contrast, Asian educational philosophies prioritize the journey of learning over the destination of getting the correct answer. Students are encouraged to explore different problem-solving strategies, understand the rationale behind them, and appreciate the beauty of mathematics as a logical and interconnected discipline. Cultural Attitudes Towards Effort and Persistence: Another cultural factor that influences the approach to mathematics in Asian countries is the attitude towards effort and persistence. Asian cultures tend to value hard work, perseverance, and resilience in the face of challenges. This mindset is reflected in the approach to mathematical learning, where students are encouraged to tackle problems systematically, seek help when needed, and learn from their mistakes. Rather than relying on shortcuts to avoid difficult problems, Asian students are taught to embrace challenges as opportunities for growth and learning. Long-Term Benefits: While using tricks or shortcuts may provide immediate gratification by allowing students to solve problems quickly, it often comes at the expense of long-term understanding and mastery. By prioritizing conceptual understanding and problem-solving skills, Asian students are better equipped to tackle complex mathematical problems and adapt to new challenges in the future. Additionally, the emphasis on process over outcome fosters critical thinking, creativity, and resilience, qualities that are invaluable not only in mathematics but in all aspects of life. Conclusion: The tendency of Asian people to avoid using tricks in math stems from a cultural emphasis on mastery, process-oriented learning, and a positive attitude towards effort and persistence. While shortcuts may offer temporary solutions, they often hinder long-term understanding and growth. By prioritizing conceptual understanding and problem-solving skills, Asian students are better prepared to tackle the challenges of mathematics and beyond, embodying the timeless adage that true mastery comes from understanding, not just memorization.
It's easier to simply think of it as taking away a single 51 and putting it aside. The you can just multiply 30*51, which is more easily thought of as 10*51*3, or 510+510+510. Then you just add 1530 and the 51 you took from the beginning, to get 1581. Think about as trying to get rid of the end part of one of the numbers that isn't letting you just multiply by 10, setting that aside, and then adding it back at the end. This would work with any number, and you don't have to depend on arbitrary rules.
To solve \(x^2 + 4x[-2] + y - 2\), when simplified, becomes: 1. Firstly, solve the multiplication in the parentheses: \(4x[-2] = -8x\). 2. Hence, your expression simplifies to \(x^2 - 8x + y - 2\). So, the simplified expression is \(x^2 - 8x + y - 2\).
i see it as having to so with quadratic equations 51(31) = (50+1)(30+1) when we distribute (50+1)(30+1), we get 50(30) + 50(1) + 30(1) + 1(1). from that we can get 5(3)(100) + ((5+3)10) + 1. look familiar?
Generalize the two numbers as a sum of a multiple of 10, and 1, i.e. 10a+1 and 10b+1. Now if you expand (10a+1)(10b+1) you get 100ab + 10a + 10b + 1 If you then factor the 10a + 10b, you get 100ab + 10(a + b) + 1
What this tells you is that the 100s digit is the product of the first digits multiplied together, the 10s digit is the sum of the first digits added together, and the last digit is always 1. If you replace a with 6 and b with 7 for example: 61 x 71 = (10 x 6 + 1) x (10 x 7 + 1) = 100 x (6 x 7) + 10 x (6 + 7) + 1 = 100 x 42 + 10 x 13 + 1 = 4200 + 130 + 1 = 4331.
This Trick is wrong.. everything is correct except the second step. In (51×31) Instead of adding just 5+3(=8) you should cross multiply the first num on top(5) and second number on bottom (1) & Cross multiply first number on bottom(3) and second num on top(1) and add both of them (5×1=5) + (3×1=3) which is anyway (5+3=8). The rest of the steps are correct. Here is another example, 11×32=? 1. Multiply last two numbers 1×2=(2) 2. Cross multiplication and adding the answers (1×2=2) + (3×1=3) = 2+3 = (5) 3. Multiply first two numbers 1×3=(3) Write the ans from left.. 2 5 3 Ans is 352 ✓
Yk there is another way similar but works on everything For example 37x96 The ones digit would be 2 with a 4 on top of the tens digit So now it’s ___2 Now the tenth digit is for 3x6+7x9=81 So now it’s 1+4 on tenth and 8 on top of hundred digit So now it’s __52 Final one, its 3x9= 27+8=35 So now its 3552 Boom works with everything

The way that I learned that you're supposed to put a place holder zero, then you're supposed to. The one then do 51 times 3, but I'm assuming it might be different based off of people curriculums.

Or you can do this: 51 ×31. Do 1×1 then 1×5 51 Then go under the first one then do 3×1 and 3×5 +155. Then add 51 to 15 206 What they did is wrong,this is called long multiplication,you times the bottom number (aka) 31,get the one and the 5 in the top,then 3 and the five,put it under then just add the answers if you dont understand just comments ill explain it better
i see it as having to so with quadratic equations 51(31) = (50+1)(30+1) when we distribute (50+1)(30+1), we get 50(30) + 50(1) + 30(1) + 1(1). from that we can get 5(3)(100) + ((5+3)10) + 1. look familiar?

This exact method doesn’t work for everything like if the tens together add to something 10 or more then you would just take the ones digit instead of the whole sum. Then add one to the product part of the number….if that makes any sense 😅
Ima answer in another way! 51× 31 =? { First we start with I × I which is equal to II {two/2} Now we do I × V {1 × 5} which is five{5/V} And now the same with the others, again, I × V {1 × 5} which is five{5/V} And now V × III { 5 × 3} Which is 15{Fifteen/XV},Now we do III × I {3 × I} Which is 3{three/III}And now add all the results} I+I+5+3+15 {btw u start from the end like he did in the video} 51× 31 = 1581 hope this helped!

He says that in the beginning. Did you watch without sound?
To solve \(x^2 + 4x[-2] + y - 2\), when simplified, becomes:

So, the simplified expression is \(x^2 - 8x + y - 2\).
Easier trick. Do 50 x 30 + 50 x 1. Works every time. Or 50 x 10 + 50 x 10 + 50 x 10 + 50 x 1. Which would = 1550. So im pretty sure this is wrong.
NO NO NO IT IS NOT RIGHT
YOUR DUMB
U r wrong ur using 50 to multiply not 51
If u used 51 that would be correct
Or do 3 x 510 + (1 x 51)
i see it as having to so with quadratic equations
51(31) = (50+1)(30+1)
when we distribute (50+1)(30+1), we get 50(30) + 50(1) + 30(1) + 1(1). from that we can get 5(3)(100) + ((5+3)10) + 1. look familiar?
What is a good math trick for finding the average of a list of numbers: 63, 58, 61, 67, 59, 59, 60, 56, 62, 63 without using a calculator or Excel.
Generalize the two numbers as a sum of a multiple of 10, and 1, i.e. 10a+1 and 10b+1.
Now if you expand (10a+1)(10b+1) you get 100ab + 10a + 10b + 1
If you then factor the 10a + 10b, you get 100ab + 10(a + b) + 1
wha...
What this tells you is that the 100s digit is the product of the first digits multiplied together, the 10s digit is the sum of the first digits added together, and the last digit is always 1.
If you replace a with 6 and b with 7 for example:
61 x 71 = (10 x 6 + 1) x (10 x 7 + 1) =
100 x (6 x 7) + 10 x (6 + 7) + 1 =
100 x 42 + 10 x 13 + 1 =
4200 + 130 + 1 = 4331.

This Trick is wrong.. everything is correct except the second step. In (51×31) Instead of adding just 5+3(=8) you should cross multiply the first num on top(5) and second number on bottom (1) & Cross multiply first number on bottom(3) and second num on top(1) and add both of them (5×1=5) + (3×1=3) which is anyway (5+3=8).

Teacher:but you need to show the work🤓
My math exam is today 😭😭
Everything should be simple, but not simpler enough
- Albert Einstein
Yk there is another way similar but works on everything
For example 37x96
The ones digit would be 2 with a 4 on top of the tens digit
So now it’s ___2
Now the tenth digit is for 3x6+7x9=81
So now it’s 1+4 on tenth and 8 on top of hundred digit
So now it’s __52
Final one, its 3x9= 27+8=35
So now its 3552
Boom works with everything
People who said it's totally wrong then went to the calculator and it was correct 😂
tysm youre a life saver also ignore the mean comments
TYY I LITERALLY COULDNT FUNCTION MY BRAIN FULLY TODAY TYYY
This answer is Rong 😂
no
That’s not how you spell wrong,wrong is spelled WRONG
You spelt wrong wrong
As a teenager we don't need that trick anymore
Thanks for helping me with math
Edit:also I don't get the first step
just put a 1 easy duhh
You Deserve a sub
Yes is fake it don’t work for math
Yes if you times two numbers it doesn't always end in 1
he literally said for multiplying numbers that only end in one
Bro this guy actually help me a loy
51 x 31 is 1581 am i correct?
yep
What about 91x51
no
Only happens when the number has 1 at its ones place
Like it makes sense IM NKT USING THAT FOR MATH!
thank you this will help alot
I changed my comment, and i changed my mind.
I ain’t;t reading that
I'm Asian and you just say a thing that I don't even understand. Why need to do that when you can do it normally and easier by just use your brain?
I live in the smartest country in the world with an iq of 127 for my age, i understand physics beyond secondary school, and math p6 (im p5), i’ve won many awards for my math. What the f*ck do you mean, or maybe idk coz my math doesn’t go beyond a t4 p6 student
Bro didn't get the likes he wanted 💀
This is what I needed today
Im an asian and...
THIS IS ALL WRONG!
Nobody ASK
I had googled the answer, don’t ask why😨
The way that I learned that you're supposed to put a place holder zero, then you're supposed to. The one then do 51 times 3, but I'm assuming it might be different based off of people curriculums.
I remember this at 3rd grade!
no you have it on 4th grade you aren't a 5th or 7th dummy
Same
Ohh good idea , please can you show an other problem

Im good with the butterfly tatic :)
What if the ones digit did not have the same number like if we do 87x89 can we still use this method? Or no
91*91 how
Or you can do this:
51
×31. Do 1×1 then 1×5
51 Then go under the first one then do 3×1 and 3×5
+155. Then add 51 to 15
206 What they did is wrong,this is called long multiplication,you times the bottom number (aka) 31,get the one and the 5 in the top,then 3 and the five,put it under then just add the answers if you dont understand just comments ill explain it better
thank youu
FAKE
I DID IT ON
81×22
I DID IT WITH THE TRICK ITS 1602
I DID IT NORMAL 1782
THIS VID IS WRONG THUMBS DOWN
I feel sorry for your math skills
I hope ypu never reproduce
you are so stupid it says multiplying numbers that both end in 1
Does this trick only work with numbers that end with a 1?
Not applicable in all digits
i see it as having to so with quadratic equations
51(31) = (50+1)(30+1)
when we distribute (50+1)(30+1), we get 50(30) + 50(1) + 30(1) + 1(1). from that we can get 5(3)(100) + ((5+3)10) + 1. look familiar?
Not all

(50+1)(30+1)=1500+50+30+1=1581
I am low key restarded, I am going into the 8th grade and can BARELY do long division.. I am getting excellent grades on almost all my subjects except math.. I didn't study during covid and I think that messed me up. My friends think I'm genuinely aucistic or somn...
Yeah that's correct 💯 only works when last digit is-one
is this trick is only applied for the no which have 1 at the end
I know this one but it was pretty good
Thanks for the hack ima need it 😂
Or we can just do the power of 10, (example) the number 1 followed by n zeros, where n is the exponent and is greater than 0;
This exact method doesn’t work for everything like if the tens together add to something 10 or more then you would just take the ones digit instead of the whole sum. Then add one to the product part of the number….if that makes any sense 😅
it only depends on the number
Only works on specific numbers
Does it work for numbers ending with 1?
I understand "pt pt pt pitpt mulptili addpt 81" lol
WE INDIANS ONLY TAKE THE HARD CORE WAY!!
when the teacher says to show your work
you:
Ima answer in another way!
51×
31
=?
{ First we start with I × I which is equal to II {two/2} Now we do I × V {1 × 5} which is five{5/V} And now the same with the others, again, I × V {1 × 5} which is five{5/V} And now V × III { 5 × 3} Which is 15{Fifteen/XV},Now we do III × I {3 × I} Which is 3{three/III}And now add all the results}
I+I+5+3+15 {btw u start from the end like he did in the video}
51×
31
= 1581
hope this helped!
Nerd
@@TheRealAimbotVoid if you wanna know no I'm not a nerd I'm js smart unlike you
As a very good person at maths this makes it alot confusing
100 in math ❤❤
It's easy but I think I'll stick with the normal one... Because you have to show solution in my test.
Tip: This only works if both numbers end in 1
Do you know this method?
Example:
29×2=n(number sentence)
(20×2)+(9×2)
(40+18)
Answer:58
DUDE THANK U
Our school does this method but its not the we need to + it to find the answer😊😊
I don’t why I was looking for this vid ._.
We Asian don’t do this because we are smart and can do this metal brain
I kinda went to calculator and saw 465😅😅😅
Can you do same with 91 times 91(I tried but whe I calculated it was wrong(with the same trick) so try)
Can you try 18x18 using this technique
My math isn't mathing
Wait lemmie caculate
Wow ang galing mo pre😅😅
When my math isn't mathing 💀
The answer is with use the method of 51
X 31
51
+ 1530 =
1581
It's 10000% working thank you
It's a correct answer but we cannot solve it like this because the up and down the number is different so please give us answer about this solve this multiplication 43x32
and show as let's see you can do it or not
I wonder how I failed my math test using this way.
(By the way guys, don't use this math trick. It doesn't work for everything.)
This is sick
It's not working with different numbers. It has to be ones at the end
I'm Asian and my teacher taught us math tricks bro also I'm Filipino
I don’t get it where did you get the one?
Surely this would work the same if u multiply the last digits as 1x1 =1 0x0=0
