There's nothing you can throw at me that I cannot handle with some multiple of i and some multiple of j.

你们找不出任何一个我无法,用 i 和 j 的倍数来表示的矢量

Now, I've not given you any other example besides the displacement vector, but at the moment, we'll define a vector to be any object which looks like some multiple of i plus some multiple of j.

除了位移矢量之外,我就不再举其他的例子了,但是现在我们要定义一个矢量,可以表示为 i 的倍数加上 j 的倍数
