Question

Let A and B be two sets in the universal set. Then A−B equals

Answer 1

The subtraction of vector B from vector A is defined as the addition of the negative vector B to vector A.

Step-by-step explanation:

The subtraction of vector B from vector A is defined as the addition of the negative vector B to vector A. This can be written as A - B = A + (-B).

For example, if A = {1, 2, 3} and B = {2, 4, 6}, then A - B = {1, 2, 3} + (-2, -4, -6) = {-1, -2, -3}.

Therefore, A - B equals the sum of vector A and the negative of vector B.
