Q

What is the rule for Addition and Subtraction when solving an equation with sig. figs.?

A

the answer is rounded to the same # of decimal places as the # with the least decimal places in the equation.

Ex #1: 7.12 - 1.345 = 5.775 = 5.78
(7.12 has the least number of decimal places in the equation so we would round our answer 5.775 to have the same amt of decimal places. This would make the answer 5.78, which is also rounded to the nearest hundredth, DONT FORGET TO ROUND)
Ex #2: 5.7 + 2.11 = 7.81 = 7.8

Q

What is the rule for Multiplication and Division when solving an equation with sig. figs.?

A

the answer is rounded to the same # of sig. figs. as the # used in the calculation with the least sig. figs.

Ex #1: 17.85/2.13 = 8.38028 = 8.38
(You divide the 2 #’s and get that long number but since 2.13 is the # with the least sig. figs. you round your answer to get the same amt of sig. figs., which is 3, this will lead you to get the answer 8.38)
Ex #2: 0.0561 x 0.030 = 0.001683 = 0.0017 (rounded)
