How do you do sig figs when adding and multiplying?
When you add or subtract, you assign significant figures in the answer based on the number of decimal places in each original measurement. When you multiply or divide, you assign significant figures in the answer based on the smallest number of significant figures from your original set of measurements.
How many sig figs are in a problem with addition and multiplication?
The following rule applies for multiplication and division: The LEAST number of significant figures in any number of the problem determines the number of significant figures in the answer. This means you MUST know how to recognize significant figures in order to use this rule. Example #1: 2.5 x 3.42.
What is the rule for rounding when multiplying and dividing?
Where should we round it off? That answer comes from the rule for significant digits used in multiplication and division: Round the answer to the shortest number of significant digits in the numbers you are multiplying or dividing.
How to determine how many SIG figs are in a number?

Rule #2: Leading zeroesare neversignificant. Rule #3: Trailing zeroesare only significant if a decimal point is presentin the number.
How to calculate significant figures with addition and multiplication?
Significant Figures With Both Addition And Multiplication Operations Example: Convert 73˚F to K (Kelvin) STEP 1: Convert 73°F to °C. 9 × ° − 5 ( 32) ° = F C In this equation, 32, 9 and 5 are “exact” numbers (see rule 1). C = = ° C × = × − ° = 22.8 23 9 5 (41) 9 5 (73 32) Note that in this equation, 73 contains 2 significant figures and the
