Do the calculation using all digits and round the final answer: 1.3 × 3.04 × 5.46 = (1.3 × 3.04) × 5.46 = 3.952 × 5.46 = 21.57792 Use the digit following the hundredths digit as the deciding digit; the hundredth digit is the second digit after the decimal point so the deciding digit is the third: the deciding digit is 7 which is greater than or equal to 5, so round up: 21.57792 → 21.58 to the nearest hundredth.

When you enter a two-digit year value, Excel changes a two-digit year less than 30 to 20xx and a two-digit year of 30 and greater to 19xx. Use four-digit years to ensure that Excel interprets year values the way you intend, if necessary.
