14

Explanation:

First start with grouping, turn |-4| changes to 4 due to it being 4 places away from 0. then go over to (-7+1), add 1 to -7, which turns it to -6. By this point we have 4+4--6, we must turn --6 to +6 because subtracting a negative is the same as adding a positive. By this point we now have 4+4+6, by now it is relatively simple, add 4 to 4 which is 8, now add 6 to 8, then we have the answer 14.
