The rules for addition are as follows:
- The sum of two negative integers is a negative integer
- The sum of two positive integers is a positive integer
The rules for subtraction are as follows:
- If they are two positive numbers, do it normally
- If there is a negative and a positive ,change it to addition and switch the SECOND integer sign

What operations are closed for integers?
Addition, subtraction and multiplication.
How is subtraction and rational numbers are different from adding?
They are different in the same way that subtraction of integers is different from their addition.
Rules for integers?
Placing a question mark at the end of a phrase does not make it a sensible question. Try to use a whole sentence to describe what it is that you want answered. Your "question" sheds no light on what rules for integers you are interested in: rules for addition, subtraction, and so on; rules for multiplying numbers with integer indices, and so on.
What are the addition properties and subtraction rules?
Inverse and idenity
What are the 4 rules in maths?
Addition, subtraction, multiplication and division
How are addition and subtraction of integers related?
Addition and subtraction are inverse functions.
How is the subtraction of integers relate to the addition of integers subtraction?
they both have something to do with positive and negative
Who discovered addition and subtraction of integers?

What if the numbers in addition and subtraction in integers are the same but the sign is different?
You are likely to get a different answer.
Explain how the subtraction of integers is related to the addition of integers?
Subtraction of integers is essentially addition of integers except the second integer is inverted. For example: 5 + 3 = 8 is a simple addition of integers. 5 - 3 = 5 is a simple subtraction of integers. It can be expressed by inverting the second value (the one right after the subration sign) and then switching the subtraction sign to an addition sign. So it would look like: 5 + (-3) = 5. Note that (-3) is the opposite of 3. So to do a more confusing subtraction problem like: 55 - (-5), we could rewrite this as: 55 + -(-5). From here it's easy to see that the two negatives cancel out. 55 + 5 = 60.
How is estimation helpful when adding and subtracting decimals?
It is difficult to answer the question because, for addition or subtraction, it is often easier to obtain the exact answer! If you line up the decimal points and then follow the rules of addition or subtraction - exactly as they would apply to whole numbers - you will get the correct answer!Estimation may be useful to check your answer if you are poor at addition or subtraction of integers. But, if that is the case, your estimate is equally likely to be wrong!
What are the rules for dissimilar fraction?
