If the signs are different subtract it whether they give the sign of plus, and then copy the sign that has the biggest value for example-
-1 + 4, negative 1 plus positive 4 it's unlike sign so subtract 4-1=3 the biggest number is four so the answer is Positive 4 we can write it as 4 or +4.
Like signs.
If the signs are same add it and copy the sign for example -9 + -6 the signs are same negative so 9+6 =15 and copy the sign so -15
