Well, honey, let me break it down for you. The number 4030 has three significant digits because the zeros are sandwiched between non-zero numbers. So, count 'em up and you'll see that there are three digits that actually matter in this number. Hope that clears things up for ya, darling!

Integers ending in 0 are always ambiguous. It is not possible to tell whether this number is accurate to the nearest tens (3 significant figures) or to the nearest integer (4 significant figures).
