state the rules governing the number of significant figures that result from each of the following operations addition and subtraction; mutiplication and divison

Verified Answer :

Adding and subtracting it's how many are behind the decimal, and multiply its how many digits

  • The number of significant figures in the result for addition is equal to the significant figures in the number with the least decimal point:

For example:

\(0.998 + 1.8 \approx 2.8\)

  • The number of significant figures in the result for subtraction is equal to the significant figures in the number with the least decimal point:

For example:

\(68.950 -3.14 \approx 65.8\)

  • The number of significant figures in the result for multiplication is equal to the number with the least significant figures:

For example:

\(0.67\times 4.654 \approx 3.1\)

  • The number of significant figures in the result for division is equal to the number with the least significant figures:  

For example:

\(=\frac{45.876}{3.3}\approx 14\)
