Adding two numbers with different signs means subtracting the two absolute integers (without sign) and vice versa.
The sign of the sum will be the same as the number with the greatest absolute value. -9 + 4 = -5 -4 + 9 = 5
Just multiply without the sign. Then add a minus sign to the result.
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.
You find their difference. The answer has the sign of the number with the larger absolute value.

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.
The examples show that, to find the of two integers with unlike signs first find the absolute value of each integers.
You find their difference. The answer has the sign of the number with the larger absolute value.
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)
You subtract the smaller from the larger and give the answer the sign of the number with the larger absolute value.
if the signs are the same you must add its opposite.
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.
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.
-You must memorize -To add 2 integers with different signs, find the difference of their absolute value -To subtract an integer, add it's opposite
