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.
true
One of the rules of significant figures is that leading zeros are not significant; therefore, 0.00034 will only have TWO significant figures (3 and 4).
Significant numbers, or significant figures, are used to express the precision of measurements. The rules include: all non-zero digits are significant, zeros between non-zero digits are significant, leading zeros (before the first non-zero digit) are not significant, and trailing zeros in a decimal number are significant. In addition, trailing zeros in a whole number without a decimal point are not considered significant unless otherwise indicated. Always round calculations to reflect the precision of the least precise measurement involved.
the precision of the answer must have the same number of significant digits as the measurement with the least significant digits- the site explains the rules and how to identify significant digits
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.

Salient rules means those rules likely to have a significant effect.
