# What is the 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 + 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.

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...

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)

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.

Any integer can be divided by any non-zero integer, and the result is a rational number.

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.

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

ADDING: same sign, add and keep that sign. opposite sides, subtract their absolute values and use the sign of the number with the larger absolute value SUBRTRACTING: change the sign of the subtrahend (2nd number) then ADD using rules above.

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.

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.

With both positive it's positive, with both negative it's negative.

Integers are real numbers; therefore, when you multiply them you must follow the rules of multiplication. Some rules include: any number multiplied by one equals itself, any number multiplied by zero is zero and every number multiplied by two is an even number.

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)

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

when you add two positive integers the answer is always positive when you add two negative integers the answer is positive when you add one negative and on positive integer, the answer is negative subtracting two negative numbers gets a negative answer subtracting two positive numbers- the answer depends subtracting a negative and positive number- the answer depends, the positive number would have to be bigger than the negative to achieve a negative number, and if the positive number is less, than the answer is still negative

1. change the subtract to an add and switch the sign of the second. 2. follow rules for addition. -same sign is adding and keep the sign -different sign is subtract and take the sign of the bigger number

Rules: Unlike SignsSubtract the absolute value of the number and copy the sign of the number with greater absolute value.

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.

If the signs are the same, add the absolute values and keep the sign. If the signs are different, subtract the lesser absolute value from the greater absolute value and keep the sign of the number with the greater absolute value.

you subtract the bigger number from the smaller numberyou get your answeryou look for the bigger number an put the symbol that it has

There are an infinite number of operations for integer and different rules will apply for different operations. The question needs to be more specific.
