Answer: -8
Explanation:
3+(-4)-7
Whenever you have a +(- something), it ALWAYS becomes a -
So 3+(-4)= 3-4
Now we have:
3-4-7
PEMDAS states that you must do the subtraction from left to right. So you start with the 3-4.
3-4-7
-1-7
-8
Whenever you have a negative number minus a number , the result will always be negative.
Hence, thats why the answer is -8
