Question 11
Let $A$ be the set $\{0,1,2\}$. Let $B$ be the set $\{3,6,x\}$, where $x$ is an integer.
I multiply each number in the first set by each number in the second set.
Let $C$ be the set of all the numbers which are the results of these multiplications.
What could $x$ be such that $C$ has exactly 5 distinct elements?
