### Equal sign?

In the book, I saw an example where the final answer used an equal sign instead of a greater than or equal to sign. How important is this sign, and what is its significance?

### Re: Equal sign?

In that case, the equal sign shows the minimum uncertainty is equal to that value. If you get the greater than or equal to sign, then the minimum uncertainty is that value, but there could also be more uncertainty(any values higher than that value.)
