Who is the smartest 🤔?

There is no USA/China method. There are just different ways to simplify or develop expressions. You learn them all in school — the smart part is choosing the most efficient one to start with.

They do that in America too, you're supposed to, it's called cross cancelling.

It is not about US and China "method"... there is no such a thing. It is about having enough algebra experience to notice that both terms are divisible by 9 leading to a simpler computation. Any high school student competent in math, both in US and China, will see that.

They are both correct but one is faster

USA does the right too what’s your point?

The china method is great though

I was taught the version on the right - in the US - over 50 years ago, so...

I was taught the way on the right. By the way that is not the « China way », it is just a different way.

@kaswizofficial This guy handwriting sharp

You’re a fucking moron. Simplification is taught in US too.

9x8 =72 and it would take 13-5 to get 8 So pretty easy in 2 steps.

I used to get in trouble in school for doing it the fast way.

Both are smart and who compares this and believes that these methods belongs to those respective countries are dumb...

they’re both right and i like the china method. so simple, easy and fast.

i'm from the US, and I would simply divide through by 9 on such a problem.

Dear, if you really wanna study mathematics, the best destination is China

Step 1: Divide both sides by 9 Step 2: Add 5 to both sides

we're taught both in america, though. just depends if you want to do it the long or short way or not

I old enough to have been taught what you are calling the “Chinese” method.

Without looking at what China is going to do, I know they are the smartest. Power belongs to USA but smartness belongs to China 🇨🇳

hmm 9 (x-5)=73 >goodbye china

数字の書き方がおかしすぎる。 １１７って、読めなかった。

That's why ts maths .. many steps ,but same result Both did well

USA is very much ahead of China in this game. No competition.

TODOS los que enseñamos matemática usamos la segunda forma. La otra es sólo si estás enseñando distributiva

I took my first year of algebra in 1988, so my memory of the class is a little dim, but I'm pretty sure were learned both.

I will go with China in this case

I mean its literally just how maths work, tf China has to do with anything lmfao

Its not truly a US vs China method. I am not from China and yet still use that method.

@Padre_Obi China

Why would the “US” version not divide both sides of the equation by 9 to start? It’s what I would do, and I’m American.

The person holding the biro is smart to be honest

Whoever claims that these are typical for the US or China is definitely NOT the smartest. And now do this for =71.

This is wrong! Americans learn both methods. Smarter people can do that problem in their head with no paper. It is the individual and the person that studies the most are the smart people.
