Answer:
Seven.
Step-by-step explanation:
-3-(-8)-(-2)
Using PEMDAS, we are working with only subtraction, which means we will be moving from the left to the right.
Let's start with -3-(-8)
At first it seems like -3-8, which would be -11, HOWEVER, this is incorrect, because it is -8, not 8.
When subtracting a negative number, like we are doing in this problem, it actually turns into addition.
Therefore, -3-(-8) becomes -3+8, which is 5.
After doing this, we have 5-(-2).
Again, we are subtracting a negative number, so in actuality you want to add it.
So instead of 5-(-2), we are actually doing 5+2, which is 7.
Therefore -3-(-8)-(-2) is 7.
