The easiest way to do this is to temporarily ignore the signs and then subtract the smallest from the largest. Since they are opposite signs, they cancel each other out (meaning you'd subtract rather than add). Then add whichever sign of the largest starting number to the answer.
For instance, take -52 and 12. Since the signs are opposite, adding turns into subtraction. Put another way, adding the 12 to the -52 makes the -52 less negative (more positive). So subtract 12 from 52 and you get 40. Since -52 has a greater absolute value than 12, the answer gets the negative sign, thus you have -40. So adding the 12 makes the -52 smaller (less negative) by 12.
Or to demonstrate the other way, take 30 and -10. That is easy, since when you add a negative, you are subtracting. So 30 minus 10 is 20. Since the largest starting number is positive, you don't have to worry about the sign when you are done.

How do you find the sum of two integers with different signs?
-- write the difference between the integers without regard to their signs -- give the difference the same sign as the larger of the two integers
How do you add integers with unlike signs?
The examples show that, to find the of two integers with unlike signs first find the absolute value of each integers.
Is the answer to adding two negative integers a positive or negative?
When you add two negative integers, the answer is still negative.
What are the rules of addition?
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.
What is an example of adding two negative integers?
-4 + -4 = -8
When adding two integers with opposite signs what is the answer going to be?
The sum will take the sign of whichever number is larger (disregarding the signs). -6 + 8 = 2 6 + -8 = -2
How do we add integers with opposite sign?
To add two integers with opposite signs . . . -- Ignore the signs, and write the difference between the two numbers. -- Give it the same sign as the larger original number has.
When adding two opposite integers?
Subtract the number you first thought of.
What is the sign of the product of two integers with different signs?
for integers with tow different signs, it will always be negative in multiplying and division. for adding and subtracting, the sign is for the bigger number.
What are the rules in adding integers with unlike signs?
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.
When two integers add to zero?
Two integerss add to zero when their absolute values are equal and they have opposite signs.
How do you add or subtract integers with a different sign?
Adding two numbers with different signs means subtracting the two absolute integers (without sign) and vice versa.
What is the rule of adding integers with unlike signs?
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?
When two integers of opposite signs are added the result is the difference between the absolute values with the sign of the integer with the larger absolute value?
Yes.
How do you find the sum of two integers with different signs?
-- write the difference between the integers without regard to their signs -- give the difference the same sign as the larger of the two integers
How do you add integers with unlike signs?
The examples show that, to find the of two integers with unlike signs first find the absolute value of each integers.
Is the sum of two integers alwasys a positive?
- Always, if the two integers are both positive. - Sometimes, if the two integers have different signs. - Never, if the two integers are both negative.
