你也许认为这个误差,=372加减1的,平方根1,除以186加减。

You may think that the uncertainty in there equals the square root 1 of 372 plus or minus 1 1 divided by 186 plus or minus 1.

所以把这两个误差相加-,四分之一加二分之一，大概是0。,由于平方根，它就变成0。,但这个是错的。

So you would add up the two errors-- a quarter plus half, 7 that's about 0.7-- and because of the square roots, 35% that becomes 0.35%, and that's wrong.
