    -4 but yes when we do |-4| we get 4 since | | means we are looking for the distance between -4 and 0 so now we have 3-4 which is?

    gthug's problem was 3-|-8+4| we do order of operations: perform whats in grouping symbols first evaluate any terms with exponents perform multiplication and division as it occurs left to right perform addition and subtraction as it occurs left to right ----------------------------- example of grouping symbols: | |, ( ), [ ] so we have | | inside the | | we have -8+4=-4 so we now have 3-|-4| but |-4| means what is the distance from -4 to 0 which is 4 so now we have 3-4 but 3-4=-1 so 3-|-8+4|=-1

    First, you must go to the absolute value. Since the absolute value of a number is the distance away from 0, -8+4(inside absolute value) is 4. Then, because of PEMDAS, do 3-4 which is -1.
