I discovered this in elementary school while learning the times table. Good tool to keep in life. Notice also the two digit answers always equal 9 when added to each other.
Years ago I was a bank teller. When we balanced out at end of day and the difference was divisible by nine....there was a transposition done in math. 😊
Also our daughter had discovered that characteristic, when she was attending the first year of her primary school: she pointed out to us that the results of the so-called (in Italian) "tabellina" (= "multiplication table") "del" (= "of the") 9 could be represented as divided into two mirror-image halves, with the numeric digits of the numbers reversed. This way: 09, 18, 27, 36, 45 /// 54, 63, 72, 81, 90. And that in the first half the first numeric figure of the result increased by one unit at a time, while the second numerical digit decreased by one unit at a time, whereupon in the second half the behaviour of the digits was reversed. It was another way of discovering and describing what has been discovered by the chinese kid in the video.

That pattern can be done with your hands. If you look at your hands. You have 10 fingers. If you put a finger down there is a gap. That gap creates 2 base numbers Reading left to right, 3x9, put your third finger down and you get 2 and 7. That makes 27. 6x9, put your 6th finger down and you get 5 and 4. That makes 54.

My math teacher always told us every single day. "You are not going to have a calculator on you". Me now, i carry a calculator with me every day and if i don't understand the problem, I can just Google the answer 😂.
Fun fact: Any number multiplied by 9, its product, its individual numbers added and its sum is again added until its final sum is just a single number.. It will always be, the number 9
That’s the way I was taught to solve multiplication, so he’s doing it correctly for the ones that don’t know and understand that he’s doing it correctly

Suddenly I could do math noticably better. And subtracting is in the family of adding and dividing is in the family of multiplying.
Exqmple. 9×3, extend your fingers out and count to 3. The thirsd finger you drop and the answer reveals itself within the fingers that are up still. So in this case you put the 3rd finger down and it makes 2 and 7 which you put them together make 27
