I need to see if i worked this problem right. -8 - -7 =-15
-8+-7=-15
do i add this together aredo i subtract and get -1
Your second answer is right.
-8+-7=-1
-8+-7=-15
To determine if you worked the problem right, let's break it down step by step.
The expression you have is: -8 - (-7)
To simplify this expression, we need to remember the rule for subtracting a negative number, which is like adding a positive number.
Step 1: Replace the double negatives with the positive form:
-8 - (-7) = -8 + 7
Step 2: Add the numbers together:
-8 + 7 = -1
So, the correct answer is -1, not -15.
Therefore, your original answer, which is -1, is correct, while the other option, -15, is incorrect.
