You can put this solution on YOUR website! Rewrite the following using mathematical symbols:
A. Q is equal to the set whose elements are a, b, c.
Q = {a, b, c}
B. The set containing 1 and 3 only is a proper subset of the set of natural numbers.
{1, 3} ⊂ N
C. The set containing 1 and 3 only is not a subset of {1, 4, 6, 7}
{1, 3} ⊈ {1, 4, 6, 7}
D. The empty set does not contain 0 as an element.
Either this way ∅ ∌ 0 or this way: 0 ∉ ∅
If you prefer you can write the empty set as an empty pair of braces {}
