bruh its 2021 and they still didn't teach us this wtf its a W for online classes and tests with camera

There are a lot of ways to multiply in your head. The one I found easiest and always stuck with me is to simplify any multiplication by adding together two easier ones. For example if you have 118×210 that is just 118x200+118x10 which is really easy to calculate.

I know I'm late. But I'm having a problem. I gave a friend of mine this problem

Whats 37% of 347. He got 136. But using Google it Gabe 163. So what's the issue?

Mary Cummings

where's the promised link?

Aden Aden

thx this is supermegaultra ez peasy hold the lemon no squeezy sauce now!!!!!!!! thxthxthx

jessica DaCosta

No you are telling me all this time going to Maths class it wasn't making any sense

soboro sunny

or for example

20% * 18

cross out zeros

then it will be

2 * 18

which leads you to 36

then apply 20% as .2 (no zeros allowed)

and then put the decimal places back toward how much spaces back .2 (or any decimal your applying with)

so it is one place to the left so

change 36 to 3.6

its more logical but I find ur way easier

Adrian Soto

Does this apply just to numbers with “0” at the end?

Sue Elliott

Some Aussie knows his math. Thanks mate, pretty good

xx.mariaa4

this is super helpful im really happy im getting this thank you very much

Tony Baker

I would do it slightly differently :- (13 X 5% is 65%) therefore 5% of 82 is 4.1. so 65% of 82 is 4.1 X 13 = 53.3

The Twin Shunters

Thanks

Pretendthisnamewascool

I could never do it this way because I gotta do it the "correct way". So that crosses out any other way or shortcut there is because I need to do it their way. Hey, at least I'm not like some people who already graduated because I'm still in middle school. That's one good thing.

.20 x 180= 36

.50 X 40= 20

.20 x 18= 3.6

.30 x 12 = 3.6

30% of 60

30 X 60 = 1800

1800 ÷ 100 = 18

20% of 130

20 X 130 = 2600

2600 ÷ 100 = 26

65% of 30

65 X 30 = 1950

1950 ÷ 100 = 19.5

Somewhere Unimaginable

bro this is the best short cut I ever seen

arosha mustafa

An even easier trick is, if you have 15% of 200. Take both numbers and multiply them, then take your answer and divide it by 100 because *per*cent per hundred. I swear it will work every time

I owe you soooo much...

Literally this has been my math subject for about a week, but I’ve just been using a calculator bc of remote school and you can get away with that stuff. Now, I have to go back to school and my 2 brain cells can’t handle this. I even had a small panic attack. And then I remembered that the internet exists and here I am now, finally somewhat understanding my math topic. (I was actually thinking of breaking a finger so I could skip school)

Santiago Tamayo

Thanks so much for the extra help my teachers at my school didn’t teach me that method and now I feel robbed I was really struggling until I saw this video so thanks so much from the U.K

I understand the entire methode but you said that the spectator thinks about a number card.

But in the video they pull a random card out of the deck?

Soo... Where is the thinking part of this Trick? Bcs they chosen card is a random pull, that means we can't Manipulate them with Sentences like "Think about a number" Or smth

jo breath

Thanks so much! I have been following you for long time and I can say that you are a true Master! this trick for its simplicity and power really impressed me ... since yesterday I started studying it to understand the different possible applications.

For example I tried to divide the whole deck into two piles, putting a sign between them, for example a Joker; we construct the sum of one of the two piles so that it gives a total of 10 (therefore equal to zero) the second pile contains the rest of the total and it will be this that will be used to make the spectator choose the card; in this way we will have to count only about twenty cards to know which card the spectator has chosen. While we will go faster (for the pile where we already know the zero quota) in the phase of memorizing the cards. after knowing which card is chosen by the spectator, we will join the two piles and ask the spectator to insert his card at any point in the deck ... at this point we can choose any type of ending we want.

To start the performance we show the entire deck of cards, to point out that it is already mixed and with the excuse of removing the Joker we divide the deck into two piles resting there on the table. we will ask the spectator to choose one: if he chooses the one where we already know the total, we will ask him to mix it further and keep it aside because we will use the other pile; vice versa, if he chooses the pile that we must use to make him choose the card, we will ask him to mix it, extract the chosen card and place it on the table; at that point we will be able to start our phase of memorizing the cards with the pile from which the spectator has chosen his card, continue with the other where we already know the total sum and continue as described above.

Just one more thing: Who is the creator of this trick? and which is a best book to buy?

Thanks a lot again!

Kadir Doğan

if you want to force a number , you can say : think of any number between 1-10 . okay got it? if you get it , i want you think any suit . got it? okay so if you get it , take the deck and take out your card and then put it in your pocket or on the table ( it depends on the moment).

you're okay now. you can do the trick . it's really nice . i liked it.

Can i do this trick without the face cards

satvik singh

Stephen Jones

You could make this an "any card" trick like this: If they really make a free choice and your sum ends up zero (indiciating a 10 or face card), then remember the bottom card as a key card, cut the cards (or have them do it) and bury their card. As you "hunt" for their card (you actually spot it quickly) then announce, it's a face card or "I think you picked a high number" then reveal their card.

try doing 4x6

this way

this video is frustrating because I want to learn the mathematical principle but the narrator is speaking so quickly

it comes across as mumbling.....can't understand a word he says.....

I m 6 year plz support me I teach kid

All the examples have numbers 3 or below, why would you show something like this without examples of how to carry 10's over when it adds above 9. Show and example of 278 x 88 please because I've tried it amd its a mess and does not work

Does this only work for 2 digit?

so with 19 X 19 it seems to work using +9 for both giving 280 +81... with 99 X 99 it seems as if you have to use -1 for both giving 9800 + 1 (99-1 = 98 then -1 X -1 = 1).. it seems as if I have to solve it to figure out whether to use +9 or -1.. is there a rule to remember here?

Oh my God!! Amazing!!! Thank you so much!!!

It’s way harder than the original sum

The only weakness of this method is "Show your work."

You are making money on patron using the ancient Vedic mathematics without even giving due credit. Shame on you.

I need an "Australian English" tutorial before this. Can’t understand the shitty pronunciation.

when yoou multpily two of the same numbers ending with 5 (25x25 for example), take first number (2) and multiply it by itself plus 1 (2 x (2+1) =6 ) add 25 at the end: 25x25=625

75x75= (7*8) & 25=5625

15x15= (1*2) & 25=225

and so on

calculator

Going into negative numbers..... asking for failure

The last example is 15 x 15. This is raising 15 to the power of 2 ("squaring" 15).

Turns out that there's an even better and faster trick for "squaring" a number that ends in 5 (that is, multiplying a number that ends in 5 by itself).

The trick for this is to use the number without the 5 at the end and multiply that number by 1 more than the number and then attaching 25 to the end of the multiplication result.

For example:

15 * 15 = (1*(1+1)) and attach 25 to the end = 225

25 * 25 = (2*(2+1)) and attach 25 = 625

35 * 35 = (3*4) and attach 25 = 1225

45 * 45 = 2025

55 * 55 = 3025

...

125 * 125 = 15625

Notice that they all end in 25 because it is merely attached at the end.

What the hell?!

All the way through high school and 5 years at uni and I never was shown this technique?! ?

It's so simple and intuitive!!

I'm actually kinda angry I was never shown this at school.

i knew that 13 times 13 was 169, decided that was close enough

Does one really needs this for base 10?

Woww amzing sir..plz make more video

9 x 9 my brain: 41

U helped me with my homework thnx bro

Real good method if you can remember the longer method.

My method is simpler.

14 x 13 = 14x10 + 14×3 = 14×10 + 10×3 + 4×3 = 182

9×18 = 10×18 - 18 = 180 - 18 = 162

15 × 15 = 10×15 + 5×15 = 10×15 + 10×5 + 5×5 = 225

Basically break down the number on the right to be 10 or multiple thereof and multiply with on left.

Work out what remains on the right, and multiply on left. If this 2nd multiply is too complicated, repeat previous simplification.

I do similar for the simple numbers i cant remember, by substitute it with a number i do know and the just add.

E.g i forgot 4x8 but i know 4x6=24

So 4x8 = 4×6 + 4×2 = 24+8 = 32

I need some mathematicians to show a proof ofthis method?

too complicated

TY.

/

This video sharing is really good. I have a math video similar to yours.

I was already good with my mental math but you now gave me a 2nd option on mentally multiplying fast.

Thank you :D

My grandson learned this in 2nd and 3rd grade.

Thank you!

This makes learning mathematics interesting!! Thanks ??

This is amazing! So helpful. I never was good at mental math in multiplication now I am. Thank you.

Omg this is amazing

Sound still very very complicate to me. I learned in school: I should calculate 14 x 10 which is simple because it needs only one single nill to add = 140. And than I multiplicate 14 by the leftover 2 = 28. The result is 140 + 28 = 168 (making a total where one side is having a 0 in the end is simple as well). This works with bigger numbers also very well, 'cause you can use x time 100, x times 10 and the leftovers. So my bases are ALWAYS 10, 100 and so on. Sorry - was in school in Saxony, where one tried already for a long time to bring everybody up to his highest achievable leve.

I remember thie trick from a vendor before when i asked him why he doesnt use calculators

Very good.

bumk

This is ancient Vedic Mathematics. A few thousend years old knowledge from India.

There are a number of ways to do these problems, and for a person who has an interest in numbers, this is enlightening ... I'm always open to find new ways(I studied Speed Math in College) ... I understand the importance of "knowing what you're doing" ... great

BUT does teaching this in school particularly garners interest in numbers, among those who basically, don't like math?

The EGGHEADS always had ways to do things that often would others' heads spinning ...

Is this teaching supposed to stop the spinning?

Stop blaming your teachers and learn what a curriculum is. They can't just teach whatever they want.

17x12=17x(10+2)=170 + 34 = 204

Me to calculator : how u doin

????

Wow!! Thank you so much sir???

realy nice... but youre nasal voice it's realy hard to bear dude...

How you get 300?

but we have calculator and alexa.

1k more to 1 million !!!!!!

so it works like: 10 base: 10 (10+a+b)+ab.... 20 base 20 (20+a+b)+ab.... 30 base 30(30+a+b)+ab. 40 base... and so on, right? cool anyway!!! thanx!

Why make it complicated

I always stick with the same formula and try my own sums but I am always way off

i just take the 10 out of the first 14 number and x it by the 17 which give us 170 and x the 4 x17= 68 and add them to get 238. but i have a photo memory and can see the numbers in my head.

I wish vedic maths was our actual basic maths...every single person would start loving maths why humans wants to make everything complex ;-;

An thats cool...i loved math but very slow but now i older i se how this guy make it faster and nice way to explain...awesome.

The way I would do it is take 4 away from the 14 first, so it's only 10x12=120. Then use the 4 afterwards, so it's 4x12=48. Then add both answers up 120+48=168. That's how my brain finds it easiest. But schools sometimes want you to show your work their way and it messes people up.

Thank u sir

????????

OMG MY MIND IS BLOWN

oh wow

Fascinating work with numbers. Thanks

Isn't this just the distributive property?

Please make your voice more clearer

*I think these are really easy ones to do in your head

They are not easy in my head but thanks for the condescending tone

JESUS LOVES YOU!!! He loves you so much that He hung on a cross and took upon Himself all the sins you would ever commit, the question now is “Do you love Him”? How do you genuinely show your love to someone? What is the greatest showing of love? The answer is sacrifice and then time. Jesus Christ paid the cost for us, through His sacrifice on the cross that we may live a life of health, deliverance and prosperity.

How can you pay Him back? You can pay Him back through spending time with Him, thanking Him for the privilege of seeing another day, and by reading His word “The Bible”. He offers you the free gift of eternal through having a relationship with Him, and partaking in this relationship immensely benefits you . He protects, guides, provides, heals, delivers, prospers, blesses you, and so much more. A true, authentic relationship involves communication on both sides. Jesus Christ is often taken for granted, many don’t give Him the slightest of acknowledgement, regardless He is still merciful and loving.

Seek Him, acknowledge you’re lost without Him and destined for destruction, believe in your heart wholeheartedly what He did for you on that cross and His resurrection. Confess with your mouth that He is Lord, and you’ve taken your first steps on that straight and narrow path to eternity in heaven with Him. And in this process your life will never remain the same, He will give you the Holy Spirit and grace, which will transform you and enable you to overcome sin, temptations and addiction and live a life that shows your love for Him. Slip ups happen, no one is perfect, but through asking for forgiveness and by His grace it will occur less and less. And you will enjoy pleasing Him and living a righteous life. You have everything to gain in Jesus Christ.

Have a blessed day!

I don't understand.

May be you are huring up or may be I am rother drinking.

(10+a)(10+b) =100+10(a+b)-ab= 10(10+a+b)+ab... it works...

Same as technology, they try to find the easy to get ...

Awesome, it’s just that you’re 50 years too late. Wish I had you for a teacher- yesteryear. Thanks mate.

A number represented with a dash in front of it is a negative number. I.e. -9 is a negative 9, never a minus nine. My college math teacher would have immediately failed you for saying minus nine!

it's saddening to think that teachers don't teach this method instead we learn it through youtube or by just finding out ourselves.

the way i do 14x12 IN MY HEAD IS....

14 x 10 (because i use something quick and easy)

this gives me 140

and i'm left with 2 lots of 14

so.. 14 x 2 is also easy..... 28

i add 140 + 28 168 Piss easy

in my opinion this is faster and less to remember than what he showed, but hey... Each to his own

LMAO !
