Use of significant figure rules helps us express values with a reasonable amount degree of precision. When multiplying or dividing, the number of significant figures retained may not exceed the least number of digits in either of the factors. Example: 0.304 cm x 73.84168 cm. The calculator displays 22.447871. A more reasonable answer is 22.4 cm2.

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. For example, 54.7511 round to the tenths place becomes 54.8.
