A negative times a negative equals a positive A negative times a positive equals a negative A positive times a positive equals a positive
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).
for algebra, + times + equals -, - times - equals +, add finally two different signs equal -. hope i helped!! :)
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 graph of the first form passes through the origin while the second does not - unless c = 0.
true
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.

According to Chargaff's rules, the amount of adenine always equals the amount of thymine in a DNA molecule. Similarly, the amount of guanine always equals the amount of cytosine. This principle is fundamental to the structure of DNA and base pairing.
Salient rules means those rules likely to have a significant effect.
rules for calculating S.F. are: 1,all non zero digits r significant 2,
Use the rules of significant figures to answer the following : 22.674 * 15.05. Answer: 341.2
all non zero digits are significant .2.zeroes betweenother significant.
rules to follow in determining the number of sigificant * zero's are not significant at the end of the whole number which does not have a decimal point * EXAMPLE: 3400 ( 2 sf's) 2000 (2sf's)*

If they did not use rules all their calculations would simply lead to random digits!
No, exact quantities are not considered when applying significant figure rules. Exact quantities are known with complete certainty and do not impact the uncertainty associated with measured quantities. Significant figures are only counted based on measured values.
