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.
Add the numerals and keep the sign. Examples: +9 + +3 = +12 -5 + -6 = -11 Just in case this is your next question: to add integers with different signs, subtract the numerals, and use the sign of the larger number.
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.
-- write the difference between the integers without regard to their signs -- give the difference the same sign as the larger of the two integers
Add the magnitudes of the integers (-4 has a magnitude of 4), then take the sign to the answer.
To add two integers with unlike signs: -- Find the difference between their sizes, ignoring their signs. -- Give the difference the sign of the integer with the larger size.
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)
Like signs give a positive answer. Unlike signs give a negative answer.
One rule is that the product of two integers with unlike signs will have a minus sign for the product.
Positive and negative signs are unlike one another.
use the number line
if the signs are the same you must add its opposite.
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.
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.
If the two signs are the same it is positive but if they are both different itis negative
Two integerss add to zero when their absolute values are equal and they have opposite signs.
The answer depends on what you wish to DO. And since you have not bothered to share that bit of information, I cannot provide a more useful answer.
