Because otherwise you would only know how to subtract and add with the same integers. Not a particularly useful skill unless just those integers turned up!
It is important to add and subtract integers: to get a new integer value in mathematics .
If the integers have the same sign (poitive or negative) you should add them together. If they have a different sign you subtract the numbers and the answer will take the sign of the number with the greatest absolute value (the number farthest from zero on a numberline) in the problem.
First, subtract the absolute values of the integers, then use the greater absolute value's sign.
to subtract an integer, add its opposite or additive inverse.
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.
You subtract the smaller from the larger and give the answer the sign of the number with the larger absolute value.
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.

you can add subtract multiply and divide them.
if the signs are different then u put the larger sing down then u subtract if if the signs are the same then u put the same sign down then u add
to subtract an integer, add its opposite or additive inverse.
If the signs are the same, add the absolute values and keep the sign. If the signs are different, subtract the lesser absolute value from the greater absolute value and keep the sign of the number with the greater absolute value.
If the number has a + sign then you add it, if it has a - sign, then you subtract it.
