Step-by-step explanation:
Operations of addition and subtraction on lists are generally performed term by term.
[2-(-2), -3-7, 4-11, -1-0] = [a, b, c, d]
[4, -10, -7, -1] = [a, b, c, d]
Step-by-step explanation:
(a)
Using the definition given from the problem
Therefore it is true for intersection. Now for union, we have that
Therefore, for this case, it would be true that .
(b)
1 is not a set.
(c)
To begin with
Therefore
Now, given an element of it will belong to both sets, therefore it also belongs to , and you would have that
, therefore .
(d)
To begin with , therefore
