Now to the magic of figuring out how many sig figs your answer should have.

" 估计值" 关於估计值很酷的是，你永远猜不到。

And for multiplication just make sure the answer has the same sig figs as your least precise measurement.

当你不知道测量物的精准度到哪时， 估计值一点屁用都没有。

Now I know it feels counterintuitive not to show all of the numbers that you have at your fingertips, but you've got to realize: all of those numbers beyond the number of sig figs you have? They're lies.

但是0很怪，因为有时只是个占位的符号 比如说:最快的飞机可以达到时速13,000英哩， 顺带一提，它真的可以!

Now I know it feels counterintuitive not to show all of the numbers that you have at your fingertips, but you've got to realize: all of those numbers beyond the number of sig figs you have?

现在我知道不显示您手头上的所有数字感觉违反直觉，但您必须意识到：所有这些数字都超出了您拥有的信号数字的数量？
