You need the rules of multiplication as well as of addition. But multiplication of integers can be viewed as repeated addition. Thus, if p/q and r/s are two rational numbers then their sum is(p*s + q*r)/(q*s)
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.
The answer also has the same sign.
-You must memorize -To add 2 integers with different signs, find the difference of their absolute value -To subtract an integer, add it's opposite
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...

The rules are the same.

Wats are temples from South East Asia and, as far as I am aware, they do not dicatate any rules for adding rational numbers.

to subtrct integers ,rewrite as adding opposites and use the rules for addtion of integers..
The answer also has the same sign.
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.
Since whole numbers are the same as integers, there are no different rules! The only way in which the rules for natural numbers is different is that the set does not contain the additional opposites of numbers (in other words, the set is not closed under subtraction).
