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 is Adding integers and rational number rules?
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.
What are the rules for adding integers if the signs are the same?
The answer also has the same sign.
What is the rules of integers in multiplication?
Integers are whole numbers. 1 3/4 is not a integer whereas 1 is.
What are the rules for adding and subtracting numbers?
-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
