The answer also has the same sign.
if substracting by two negatives your going to add ex: -2-(-5) it would be positive 7. if your substracting with two differ numbers it you would substract and take the sign the sign of the biggest number.ex: 2+(-3) it would be-1 sice 3 is bigger than2 you take the sign of 3
Adding Integers To add integers, one must consider the following two rules to be a successful. If you want to think of it on the number line you start from 0 and when you add a positive number you...
For each pair of such integers, find the difference between the absolute values of the two integers and allocate the sign of the bigger number to it.
Put them one below the other so that the decimal points are aligned. Fill out to the right with extra zeroes, so that they have the same amount of decimals - or just imagine the missing zeroes.

to subtrct integers ,rewrite as adding opposites and use the rules for addtion of integers..

With both positive it's positive, with both negative it's negative.
They aren't. The rules are the same as those for adding/subtracting or multiplying integers. Just be careful of the decimal point's location.
To add integers with like signs you jut put the positive in front of the answer (you just add and put a positive sign in front of it)
Adding integers, if they have the same sign, add their absolute values and keep the same sign. Subtracting, change the sign of the 2nd number and the add using rules of addition. Multiplying and dividing, Divide the absolute values, if the signs are the same the answer is positive, if the signs are different the answer is negative.
The set of integers is closed under addition so that if x and y are integers, then x + y is an integer.Addition of integers is commutative, that is x + y = y + xAddition of integers is associative, that is (x + y) + z = x + (y + z) and so, without ambiguity, either can be written as x + y + z.The same three rules apply to addition of rational numbers.
