Answer:
1 or -9, depends on the problem, see below.
Step-by-step explanation:
-11--7+5
Two negatives make a positive so our new equation is:
-11+7+5
-11+7 is -4, so:
-4+5
And this leaves us with:
1
But I saw there was a parentheses, was it misplaced or was one not added? If one was not ended to the end, then the answer would be different.
(-11)-((-7)+5)
-7+5 is negative 2, so:
-11-(-2)
Once again, two negatives make a positive, so our new equation would be:
-11+2
Which gets us:
-9
