Addition And SubtractionThe result should have the same number of significant figures, after rounding off as the reading which has the least number of significant digits.Example: 7.9391 + 6.263 + 11.1 = 25.3021Since the least precise value is 11.1 which has 3 significant digits so the answer ...
Addition and Subtraction with Significant FiguresFor each number, check the number of significant figures to the right of the decimal point (in the decimal part). Identify the LEAST number of significant digits. Add or subtract the numbers in the usual manner. When you get the final sum or ...
But in the end, the answer must be expressed with only the proper number of significant figures. After addition or subtraction, the result is significant only to the place determined by the largest last significant place in the original numbers. For example,...

from the 1st non-zero digit located on the left. These numbers are reliable and necessary to indicate the quantity of a length, volume, mass, measurement, and so on. Arithmetic operations such as addition, subtraction, multiplication, and division are used while calculating significant figures. ...
Significant Figures and Exact Values The Significant Rules figures we are covering in this lesson must never be applied to “Exact Values”. In the previous example of the estimated crowd size, we were given the five figure value of 15 000, and worked out that it had only two Significant ...

Next, do the subtraction. 2.5 − 0.11 = 2.39 Because the rules for significant numbers in addition and subtraction are the same, we only need two significant figures in our answer. This step’s last significant figure will be underlined as well: 2.39 ...
