Question
Explain how you can determine the sign of the sum of two integers if one integer is positive and the other integer is negative.
Solution 1

To add integers with different signs, keep the sign of the number with the largest absolute value and subtract the smallest absolute value from the largest.

Step-by-step explanation:

So, here's an example.

Lets say you have this problem:

-4+5

The answer would be 1 because when you add integers with different signs, you keep the sign of the number with the largest absolute value and subtract the smallest absolute value from the largest.

Here's another:

7-2

The answer would be 5 because you keep the sign of the number with the largest absolute value and subtract the smaller absolute value from it.

Solution 2

Sum will be positive if the positive integer has greater absolute value and the sum will be negative if the negative integer has greater absolute value.

Step-by-step explanation:

We have to determine the sign of the sum of two integers if one integer is positive and the other integer is negative.

We have two integers one with negative sign and other with positive sign.

Step 1:

First we find the absolute value of the two integers.

Step 2:

We find the sum of two integers by subtracting the absolute values.

Step 3:

The result takes the sign of the integer with the larger absolute value.

Thus, the sum will be positive if the positive integer has greater absolute value and the sum will be negative if the negative integer has greater absolute value.
