significant figures are the digits that you’re keeping track of. In the number $15,200,000,000 we would say that the first three digits are significant, and the rest are rounded off. Any time you write a number, you should round it off so that the insignificant figures become zeroes.

There are five rules for identifying significant figures. 1) Non-zero digits and zeros between non-zero digits are ALWAYS significant. 2) Leading zeros (zeros at the beginning of numbers) are NOT significant. 3) Zeros to the right of all non-zero digits are only significant if the decimal point is shown.

Significant Figures Rules - a Guide
Round down whenever the digit following the last significant figure is a 0,1,2,3, or 4. For example, 30.24 becomes 30.2. Round up whenever the digit following the last significant figure is a 6,7,8,9 or a 5 with any nonzero digit at any place after it. For example, 22.49 becomes 22.5.
