The rules for addition are as follows:
The rules for subtraction are as follows:
Addition, subtraction and multiplication.
They are different in the same way that subtraction of integers is different from their addition.
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.
Inverse and idenity
Addition, subtraction, multiplication and division
Addition and subtraction are inverse functions.
they both have something to do with positive and negative

Inverse and idenity
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.
You are likely to get a different answer.
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!
