我知道你认为手很难画，但是他们对于传递信息很重要，我们的目的不需要画出手的任何细节。

I know you think hands are hard, but they're quite important to convey some ideas, and for our purposes we don't need to draw hands with any detail.

我把自己的手放在他的手上，“你真的认为是吗？”

I put my hand over his. "You think that's it?"

具体的来看考虑用长除法?如果你能在纸上做长整除现在就举起你的手。会有人举手吗?至少我不这么认为。

To put this in perspective think about long division. Raise your hand if you can do long division on paper right now. Hands? Anyone? I didn't think so.
