To find the sum of -5 and +2, you need to add the two numbers together.
Step 1: Start with -5.
Step 2: Add 2 to -5.
-5 + 2 = -3
So, the sum of -5 and +2 is -3.
To find the sum of -5 and +2, we add the two numbers together.
To do this, you can follow these steps:
1. Start with -5.
2. Add +2 to -5.
When adding a positive number, you move to the right on a number line. Similarly, when adding a negative number, you move to the left on a number line.
In this case, since -5 is a negative number and we are adding a positive number (+2), we need to move to the right on the number line.
Starting from -5 and moving to the right two units, we end up at -3.
Therefore, the sum of -5 and +2 is -3.
So, the correct response is -3.
