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
Simple math rules state that a negative times a negative equals a positive!

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.

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

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!
