The value of the answer is the sum of the absolute values of the numbers and the sign of the answer is the same as that of the two numbers.
what is the rule in adding rational numbers
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.
The magnitude of the answer is the difference between the two numbers and it has the sign of the integer which has the bigger magnitude. I guess so?
The sum is positive.

Never.
if the signs are the same you must add its opposite.

When adding and/or subtracting, your answer can only show as many decimal places as the measurement having the fewest number in the decimal places.
Adding a negative number is equivalent to subtracting a positive number. For example, adding -3 is the same as subtracting 3. Subtracting a negative number is equivalent to adding a positive number. For example, subtracting -3 is the same as adding 3. The rule to remember is that when you have a negative sign in front of a number, it actually changes its sign.
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. Only works with two integers in a subtraction question.Example: (-32)-(+2)= (-34) / (-32)+(-2)=(-34)
how do you evaluate 5 - 7
Adding negatives is exactly the same as taking away the positive number. Alternatively you can think of it as "imagine both the numbers are positive, add them together. This number is then negative. And you're done".
