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 + x
Addition 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.

What is the rule for adding a positive and negative integers?
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...
How are the rules for adding integers applied to operations with rational numbers?
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)
What are the rules for division of integers?
Any integer can be divided by any non-zero integer, and the result is a rational number.
What are the rules in adding integers with unlike signs?
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.
What is the rule in adding positive integers?
Adding IntegersTo 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 go that much to the right, and when you add a negative number you go that much to the left. When adding two positive integers, just add like normal. When adding one positive integer, and one negative integer, it is like subtracting a positive number from a positive number. When adding two negative integers, it is like subtracting a positive number from a negative number.
