It's for determining the number of significant figures. Think of the U.S. in a map. The Atlantic Ocean is to the right. Pacific to left.
If a decimal is present, start counting from the "Pacific" (left).
If absent, count from "Atlantic" (right).
So, what are we counting? We count the first nonzero digit we encounter; and all subsequent digits.
E.G.: 432.30 gram has 5 sig figs.
6,000 has 1 sig fig.
The Pacific-Atlantic Rule states that when performing calculations with significant figures, you should always move from left to right just like crossing the Pacific Ocean to the Atlantic Ocean. Start calculating with the numbers on the left (Pacific) and end with the numbers on the right (Atlantic) to ensure that your final answer has the correct number of significant figures.

How many significant figures are in 9.090?
If the zeros are significant figures then 900 is correct to 3 significant figures. If rounding off has occurred then the answer could be 1 sf or 2sf. For example : If the original number was 903 and rounding off to the nearest ten was required then 900 is correct to 2 significant figures. If the number was 927 and rounding off to the nearest hundred was required then 900 is correct to 1 significant figure.
What is the rule you use to determine the number of significant figures in the results of addition and subtraction?
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
What is the significant figures of the number of 23.400?
There are five significant figures in the given value. It is according to the rule of significant figures which say that zeros right to the decimal point are significant and all non zero digits are significant So , all the digits in the given value are significant figures i.e 5 significant figures.
What is the rule about significant figures when multiplying or dividing measurement?
the decimal place in the quotient or product should be based in the decimal place of the given with the least significant figures
How many significant figures are in 0.041?
There are 2 because of the leading zeros rule. Zeros at the beginning of a number are never significant.
How many significant figures are in 1.0054?
4 significant figures.
How many significant figures 0.03?
There are 4 significant figures in 0.0032. Seems to be only 2 significant figures in this number.
How many significant figures in 9400?
There are 3 significant figures in 94.2.
How do you round 2231479 to four significant figures?
The significant figures are the first four non-zero digits - with the last of these adjusted if the following digit is 5 or more. [This is the crude school rule rather than the bias-free, IEEE approved rule.] So the answer is 2231000.
