*If you add two integers with different signs, how can you tell whether the sum will be positive, negative, or zero?

Please see explanation

Step-by-step explanation:

When two integers are being added there can be three cases in the answer

The sum will be positive if both the integers are positive and in case of addition of one positive and negative integer, the sum will be positive if the integer with larger magnitude is positive

The sum will be negative if both integers are negative and in case of addition of one positive and negative integer, the sum will be negative if the integer with larger magnitude is negative

The sum will be zero if both the integers have same magnitude and different signs.
