To find vinculum number I was subtracting finding the complement of 989 and cosidering the number to be 0989 I raised the 0 to 1 so my answer was 1011 , but why was the answer given 1111 ? Do I also have to raise the 0 by 1 if the next number is above 5 ?

1011 is the right answer. In fact, when you take the complement of the numbers directly preceding a number greater than 5 you have to add to 9 instead of 10.
