Answer: -8

Step-by-step 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
