Do you this the American or Chinese way?

This is basic algebra it’s not “the Chinese way”

I would do it the calculator way.

There is no American or Chinese way. What method is being used in the Chinese method? What theory is that?

Neither way! Or at all

This is not "Chinese way", that's a common mathematical theorem. The question hinges on wether you know or remember the theorem. I remember it now from one of the many math courses I took in college, but I'm pretty sure I saw it in highschool too. But I've never used it

The binomial formulas were found by Alessandro Binomi, a italian Mathematican. So that's the italian way! 🤌

The algebraic way is faster.

Don't worry, you can get out of this easily.

China way fo sho

You can do that in your head, basic algebra
