For addition and subtraction, the result should have as many decimal places as the measured number with the smallest number of decimal places.
The number 1.84 x 103 has three significant figures, 1.84. The 103 part of the number does not count when determining significant figures.

There are 3 significant figures in this number.
There are 6 significant figures in this number.
To determine the number of significant figures in the product of 0.1400, 6.02, and (10^{23}), we need to identify the significant figures in each number. The number 0.1400 has four significant figures, 6.02 has three significant figures, and (10^{23}) has one significant figure (as it is a power of ten). The product will have the same number of significant figures as the term with the least significant figures, which is 6.02 with three significant figures. Therefore, the final product will have three significant figures.
You count the number of figures from left to right starting with the first number different from 0. Example: 205 has 3 significant figures 0.0000205 has 3 significant figures 0.000020500000 has 8 significant figures
Three - all nonzero digits are not significant.

When adding or multiplying numbers, the result should have the same number of decimal places as the number with the fewest decimal places. For addition, the result should have the same number of significant figures as the number with the fewest significant figures. For multiplication, the result should have the same number of significant figures as the number with the fewest significant figures.

To determine the correct number of significant figures in a calculation involving both addition and multiplication, follow these steps: Perform the addition or subtraction operation first, and count the number of decimal places in the result. For multiplication or division, count the number of significant figures in each number being multiplied or divided. The final answer should have the same number of significant figures as the number with the least number of significant figures in the calculation.

When adding or subtracting measurements, the result should have the same number of decimal places as the measurement with the fewest decimal places. When multiplying or dividing measurements, the result should have the same number of significant figures as the measurement with the fewest significant figures.
When multiplying numbers with significant figures, count the total number of significant figures in each number being multiplied. The result should have the same number of significant figures as the number with the fewest significant figures. Round the final answer to that number of significant figures.
