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 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 is the rules in finding the number and significant figures?
rules for calculating S.F. are: 1,all non zero digits r significant 2,
According to the rules of significant figures 4.57 plus 6.3 equals 10.9 This is because the least precise value in the problem is 6.3 which is precise only to the tenths digit so the answer must a?
But according to the rules of significant figures, the least number of significant figures in any number of the problem determines the number of significant figures in the answer which, in this case, would be 11.
What are the rules in significant fingures?
Significant figures are the digits in a number that contribute to its precision. The rules include: all non-zero digits are significant; zeros between significant digits are significant; leading zeros are not significant; trailing zeros in a decimal number are significant; and in whole numbers without a decimal point, trailing zeros are not considered significant. When performing calculations, the result should be reported with the same number of significant figures as the measurement with the least significant figures involved in the calculation.
What are the rules in expressing the correct number significant figures?
all non zero digits are significant .2.zeroes betweenother significant.
