eTo add the signed numbers you have to know if they have same signs or not
If they have the same signs add them and put their sign
Ex:
2 + 5
Both numbers are positive, then add them and their answer will be positive
2 + 5 = 7
-2 - 5 =
Both signs are negative, then add them and their answer will be negative
-2 - 5 = -2 + (-5) = -7
If they have different signs, then subtract them and put the sign of the greatest in the answer
Ex:
-2 + 5 =
The two numbers have different signs, so subtract them and
