How to easily multiply any number by twelve

[@zuzana325]

I suddenly turned into maths genius !!!!! Thank you

[@choochoochooseyou]

Amazed and also annoyed no one showed me this years ago

[@Hoch134]

x13: triple the number and add the number to the right x14: quadruple the number and add the number to the right x15: quintuple the number and add the number to the right etc. x22: double the number and add the number to the right multiplied per 2 x32: double the number and add the number to the right multiplied per 3 x54: quadruple the number and add the number to the right multiplied per 5 This is only a bit easier than calculating it in another way

[@xolovestitch]

What do you mean by multiply per 3?

[@Hoch134]

To be serious, I don't even remember what I meant writing this...

[@xolovestitch]

Hoch134 LOL!

[@Hoch134]

Cherie Chan Explained my thought in the worst way possible making it unable to understand it myself. Yeah, LOL is the right word..

[@xolovestitch]

Hoch134 :p, I will try what I think it is

[@jackuhas8445]

Watched a video like this but this is so much more clear.

[@sarcasmo57]

Now I'm going to multiply everything by 12!

[@josephsmith2406]

Cool. I like the way it can be expanded to other multipliers too.

[@josephsmith2406]

Great set of vedic tricks. Your explanations are easy to follow.

[@adamsuleman9113]

Really good and it is an easy way off calculating sums! Thanks

[@dunkathletics]

you are a lifesaver thank you so much

[@adrianearl6476]

great trick!

[@perrysrawsoul]

GREAT TEACHER - thank you so much

[@AlexBiparva]

[@branimira9]

You are amazing , you are helping me so much Thank you

[@laurakeane8856]

Thats great thanks

[@shubhangikaroshe2472]

What a great idea to multiply

[@soulaandefender]

Thank you for man

[@agathabooks9578]

I had to practice a lot to get this technique down. It involved the use of a calculator and lot of mistakes.

[@camel5074]

It’s simple, it doesn’t need much practice unless you haven’t passed grade 4 yet.

[@MGKhalid]

fatima jones, here is the answer for your sum 24 x 519, simple logic, multiply 14 x519 using this method and add 5190 ( 519x10 =5190) because 24 is equal to 14 +10 , hope you got it

[@laundrydetergent8163]

9 x12 is 108

[@12pivotman]

Yes, so: 9x2=18, write 8 carry 1 0x2=0 plus the 9 and the 1 carried makes 10 write 10. 10....8 is 108

[@dafyddchapman8691]

How does this work

[@NextgenBeast93]

Quite easy.

[@kanchanthale6455]

Dude just used trachtenburg system

[@C0Z3R63]

9x12 doesnt work

[@C0Z3R63]

doesn't work on single digits

[@C0Z3R63]

I take it back i'm just an idiot

[@agathabooks9578]

Geekzilla Your not stupid. If you were you would not have discovered your mistake.

[@choochoochooseyou]

Agatha Books Very nicely said, Agatha

[@cherryontop304]

It can... You see Doubling 9 we get 18, it has two digits so we have to keep the once digit 8 and carry the tens one then we have 9 + 1 =10 so the answer is 108

[@linukelookingup4214]

Thank

[@redj285]

yall make it a song

[@simranjamba106]

well thats vedic maths from INDIA you should have given credits!

[@kanchanthale6455]

It's also in trachtenburg system

[@riqhtleft.5953]

63×12 doesn't work? What?

[@CASapanSir]

It works, 3*2 = 6 at unit place, 6*2 = 12, keep 2 and carry 1 so 2 at 10th place and 0 placed before 6 so double of o 0 Plus 6 and then Plus 1 carry over makes it 7 at hundredth place, so final answer is 756

[@taken287]

24 x 519 answer please
