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 in determining the number of 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
Why do scientists use the rules for determining significant figures?
If they did not use rules all their calculations would simply lead to random digits!

What are the rules for determining significant figures when performing addition and multiplication operations?
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.
What are the rules for determining significant figures when adding and multiplying measurements?
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.
How many significant figures does 690 have?
690 has two significant figures. The zero at the end is not significant for the purposes of determining the number of significant figures.

How many significant figures in 8.00?
There are some rules for finding significant figures. here there is a problem how many significant figures in 8.00. here in 8.00 have three significant figures. Because after decimal point they may have zeros. but we have to take this as significant figures.
