To add two integers, we need to check the signs of those two integers.
Rule: If they are with the same sign (positive or negative),first add the two numbers ignoring the sign and then put their common sign (positive or negative) before the answer.
Rule: If they are with the opposite sign (one is positive and other is negative), subtract the smaller number from the bigger number ignoring the sign, then put the sign of bigger number before the answer.
24 is a multiple of 8, 6 and 4, let we write each number as a multiple of 4.
First pair of integers is: (both are positive, so the answer is positive)
2nd pair of integers is: (bigger number 48 is positive, so the answer is positive)
3rd pair of integers is: (bigger number 32 is positive, so the answer is positive)
