Best Answer

When adding or subtracting significant figures(sig figs), the answer will be significant to the same number of decimal places as the number with the least number of decimal places used in the calculation.

Example:

12.44+1.6+133.887=147.927 ==>147.9

When adding or subtracting numbers, the answer should have the same number of decimal places as the measurement with the fewest decimal places. The final answer should be rounded to the least number of decimal places among the numbers used in the calculation. Only the decimal portion of the number is considered when determining significant figures for addition and subtraction.

Round to the least precise number. 3.4 + 3= 6.4 which becomes 6.

The smallest significant place of the numbers is rounded in either addition or subtraction (for example: 2.038 +0.12 +0.1 =2.3).

How many significant figures are there in 3400?

The number 3400 has two significant figures. The rules for significant figures can be found by using the link to our friends at Wikipedia.


What are the rules in writing significant figures?

In general, the rules for significant figures are: Non-zero digits are always significant. Zeros between non-zero digits are significant. Leading zeros (zeros to the left of the first non-zero digit) are not significant. Trailing zeros in a number with a decimal point are significant; without a decimal point, they may or may not be significant.


What is the law in determining significant figure?

The rule for determining significant figures is that all non-zero digits are considered significant, zeros between nonzero digits are significant, trailing zeros in a number with a decimal point are significant, and leading zeros in a decimal number are not significant.


The significant figures in a measurement include?

The significant figures in a measurement include all known digits plus one estimated digit. All non-zero digits are considered significant, zeros between non-zero digits are significant, and zeros at the end of a number and after a decimal point are significant.

List some rules used to determine the number of significant figures and how they differ for addition and subtraction vs multiplication and division?

For multiplication/division, use the least number of significant figures (ie 6.24 * 2.0 = 12). For addition subtraction, use the least specific number (ie 28.24 - 2.1 = 26.1)


How do you ensure the accuracy of your calculations involving significant figures when performing both multiplication and addition operations?

When performing calculations involving significant figures in both multiplication and addition operations, ensure accuracy by following these steps: For multiplication and division, the result should have the same number of significant figures as the measurement with the fewest significant figures. For addition and subtraction, the result should be rounded to the same decimal place as the measurement with the fewest decimal places. By applying these rules, you can maintain the accuracy of your calculations involving significant figures.


How would one use the rules of significant figures to answer the following 67.31 minus 8.6 plus 212.198?

To determine the correct number of significant figures in the final answer for the calculation (67.31 - 8.6 + 212.198), you first perform the subtraction and addition operations. The result of the subtraction (67.31 - 8.6) is 58.71, which has four significant figures. Adding 212.198 to 58.71 yields 270.908, which also has four significant figures. Therefore, the final answer should be rounded to four significant figures: 270.9.


How do you apply the rules of significant figures in combined mathematical operations?

When performing mathematical operations with significant figures, the result should be rounded to the least number of decimal places in the original numbers. Addition and subtraction should be rounded to the least number of decimal places, while multiplication and division should be rounded to the least number of significant figures.


Rules in determining significant figures in four fundamental operations?

The simple rule is: no more significant figures than the least accurate of the values in the computation. For multiplication and division, the result should have as many significant figures as the measured number with the smallest number of significant figures. For addition and subtraction, the result should have as many decimal places as the measured number with the smallest number of decimal places. (Rounding off can be tricky, but that would be another thread)
