to subtrct integers ,rewrite as adding opposites and use the rules for addtion of integers..
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.
If you mean integers, well if you have two integers of the same sign that you are adding, add and the sign stays the same. If you have different signs, subtract and keep the sign of the one that has more. Regular numbers you just add them.

The answer also has the same sign.
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.
Yes.
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)

the addition of integers is when adding negative and positive integers
adding and subtracting integers is when you add and minus 2 numbers
