Identify Numbers and Signs: Identify the numbers and their signs. We have a positive 8 and a negative -7. When subtracting a negative number, it is equivalent to adding its positive counterpart.Convert to Addition: Convert the subtraction of a negative number to addition. Subtracting a negative number is the same as adding the positive number. So, 8 - (-7) becomes 8 + 7.Add Positive Numbers: Add the two positive numbers. Now we simply add 8 and 7 together. Calculate: 8 + 7 = 15Verify Result: Verify the result. Adding two positive numbers should result in a positive number. Since 8 and 7 are both positive, their sum, 15, is also positive. This makes sense in the context of the problem.
