I knew this trick. Multiplying by 9 was my favorite to do in my head. Only works with 9 tho.

Totalmente inteligente 😂😂😂😂😂🙏🏻🙏🏻🙏🏻♥️♥️♥️👏🏻👏🏻👏🏻

I figured that out when I was his age too

He showed the reality of Chinese education that makes mathematics a comedy. If you can't use it right away, you'll get zero points.

1x9 = 09

The Pupil is cleverer than the teacher 😃

Ya since she was happy my guess is she taught him the trick.

It ain’t stupid if it works

Wow 😲😲😳

😮😮😮😮

I learned that any number added together and divisible by three is evenly divisible by three. So 911 equals 11 is not divisible by 3 but 9,111 equal 12 is divisible by 3 and equals 3,037. I wont make a video about it though.

Try another number

This is the most underwhelming video and pathetic comment section on earth. Math was the only subject ever that I've once got the lowest passing grade on. My education is in law. How is it a problem for anyone to multiply 2 single numbers in their head? How hard is it to figure out that to multiply a number by 9, you multiply it by 10 and subtract the original number? What is f*cking wrong with you people?

kid figured out how to hack the table, but can't recite the table now. That's the whole point of the table is to memorize it.

Little bro knows his math. Wish I had been taught that trick eons ago.

Так-то напишешь, а как устно ответишь? А???😊

I love math problems. I can do it in my head and it’s always right. 😮😅😊

Mathematics was art too, exact but unique, smart boy! Btw LoL were dumbs🤯

I think he made horizontal infinity sign next to the zero

We Nigerian had to learn the whole multiplication board from 1 to 12 and even sing it. Could have saved time.

Yeah, it's the nines trick. Works with your fingers too. But it's just a trick and it only works with 9.

เก่งสุดๆ

I hate this stupid laugh track! The video would be more meaningful, relevant in more eye-opening to the subject of math without that stupid laugh track. It's like they're making fun or laughing at the universal language of math. That is why I hate that last track!!!🤦🏻‍♂️

this is old, i used to know this 30 years ago

Thông minh đó

We learned that at school in the 80s

Это конечно хорошо,но как решать то!

I thought everybody knew this

here's an interesting quirk about the number 9. If you multiply any number by 9, then add the digits of the answer together, you will get 9.
