When multiplying or dividing, the answer will have the same amount of sig figs as the value with the least number of sig figs. If the answer has too many decimal places, round to the number of sig figs it should have. For example, 12 / 3.00 = 4 ( 4.0. 12 has two significant figures and 3.00 has three, so the answer should only have two.

Look at the numbers on which you are operating. Count up the number of sig figs in each. If one of the numbers has fewer sig figs than the other numbers, that number of sig figs will be the same number of sig figs in your answer. You must then perform the operation and round the result to the correct number of sig figs: 29.35 ( 43.678 = 1281.9493

A silly (correct) example of multiplication with sig figs is: 164 × 1 = 200 Mixed operations: If you have a problem with mixed addition/subtraction and multiplication/division, keep all of the digits until you’re finished, but keep track of the last sig fig in each step by putting a line over it.
