The rules for identifying significant figures when writing or interpreting numbers are as follows:
All non-zero digits are considered significant. For example, 91 has two significant figures (9 and 1), while 123.45 has five significant figures (1, 2, 3, 4 and 5).
Zeros appearing anywhere between two non-zero digits are significant. Example: 101.1203 has seven significant figures: 1, 0, 1, 1, 2, 0 and 3.
Leading zeros are not significant. For example, 0.00052 has two significant figures: 5 and 2.
Trailing zeros in a number containing a decimal point are significant. For example, 12.2300 has six significant figures: 1, 2, 2, 3, 0 and 0. The number 0.000122300 still has only six significant figures (the zeros before the 1 are not significant). In addition, 120.00 has five significant figures since it has three trailing zeros.

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.

How do you round 0.00076321 into 3 significant?
Two rules associated with significant figure :-. When rounding off numbers is "If the first figure to be discarded is 5 or more then the previous figure is increased by 1". Zeros must be kept to show the position of the decimal point or to indicate that zero is a significant figure. Then 0.000 must be kept to show the position of the decimal point. 763 are thus the three significant figures and no change is required as the first figure to be discarded is 2 and this is less than 5. The answer to 3 significant figures is 0.000763
