The least number of significant figures in any number of the problem determines the number of significant figures in the answer.

72 is 72.2 rounded to two significant figures.

When multiplying, the number of significant numbers in the answer should be the same as the fewest significant figures in the problem. Both 13.5 and 3.00 have three significant figures, so the answer will have three significant figures. 13.5 x 3.00 = 40.5 exactly (no need to round).

Count the significant figures in each number. Calculate the minimum of these numbers. Do the multiplication Round the product to the LEAST number of significant figures, determined above.

e A number that has only 1 significant figure can't be rounded to 3 significant figures
