Adding Subtracting Significant Figures For addition and subtraction problems, the answer should be rounded to the same number of decimal places as the measurement with the least number of decimal places. the sum of the above masses would be properly rounded to a result of 21.9 g 21.9 g. example 3.17.1 3.17. 1. determine the combined molecular mass of a glucose molecule and a maltose. Significant figures are calculated automatically. paste this link in email, text or social media. add, subtract, multiply and divide with significant figures. enter numbers, scientific notation or e notation and select the math operator. the calculator does the math and rounds the answer to the correct number of significant figures (sig figs).

The least number of significant figures in the given numbers determines the number of significant figures in the answer. example: $1.4 \times 2 = 2.8$ 1.4: 2 significant digits and 2: 1 significant digit. least number of significant digits $= 1$ so, we round 2.6 to 3 since the last digit $6 \gt 5$. addition and subtraction with significant figures. If, however, you do mixed calculations – addition subtraction and multiplication division – you need to note the number of significant figures for each step of the calculation. for example, for the calculation 12.1̲3 1.7̲2 × 3.̲4 , after the first step, you will obtain the following result: 12.1̲3 5.̲848 .
