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).

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)


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)

What are the rules for significant figures in addition?

The rules of significant figures are as follows;1) Significant figures are the first digit in the number that isn't a '0'. Doesn't matter how far behind or in front of the decimal point it is.1st Significant figure of 5098 is 5000. The first number that isn't a '0'.When you get onto the 2nd is when it gets confusing. After the first significant figure, any number which comes after it is a significant figure regardless of whether it is a Zero.Thus the second significant figure of 5098, is 5000 too.And the third? Well, it's the third number in.So the third is 5090.In addition, you add significant figures like any other number. Due to the fact that it is rounded off, however, it will not be exact.
