The correct answer is:
1983 B.C.
Explanation:
To subtract this, we can reverse the order and make the answer negative. The reason for this is that we are taking away more than we have, so we will have a negative answer.
4000-2017 = 1983
In terms of time, though, we don't deal with negatives, we deal with A.D. and B.C. The use of A.D. is for dates after the year 1; B.C. is for anything before this. Since our number is "negative," it will be 1983 B.C.
