The rule for subtracting negative numbers is 'when you are subtracting a negative number from a positive or negative, you must always add it.'Example: 3--3 = 3+3 = 6

if the signs are the same you must add its opposite.

First, change it so that the two fractions have the same denominator (by changing the fractions into equivalent fractions). Once the two fractions have the same denominator, it is simply a case of subtracting the numerators, leaving the denominator the same. Finally, reduce the fraction to its lowest terms (if possible).

-15. The rule is 'subtracting a positive is the same as adding a negative'

Yes, it does.

divide them or multiply then put a negative because to different signs make a negative to of the same signs make a positive

Like signs give a positive answer. Unlike signs give a negative answer.

The answer is 22. The rule is "adding a negative is the same as subtracting a positive." - In this case, 41-19=22

if both have the same sign the answer is positive, if they have different signs the answer is negative.

The value of the quotient of two integers with different signs is the same as if the signs were the same. Because the numbers have different signs, the quotient is negative.

Multiply two integers disregarding the signs. Then if the signs are the same, the answer is positive and if the signs are different, the answer is negative. Alternatively, if you are multiplying together a whole bunch of numbers, first find the product while ignoring the signs. Then count all the negative numbers. If the count is even, the answer is positive and if it is odd, the answer is negative.

Never.
