Significant figure refers to the number of digits that are used to report a measured quantity. The amount of a significant number in a measurement always equal to the number of digits that are known with some degree of confidence and the last number, which is usually an estimate.

When figuring out how many significant figures to go to, you always use the least amount of sig figs in the question so the least sig figs means the least precise.
