List all the subsets of the set $\{-1, 0, 1\}$.
(N/A) Let $A = \{-1, 0, 1\}$.
The number of elements in $A$ is $n = 3$. The total number of subsets is given by $2^n = 2^3 = 8$.
The subset of $A$ having $0$ elements is the empty set $\phi$.
The subsets of $A$ having $1$ element are $\{-1\}, \{0\}, \{1\}$.
The subsets of $A$ having $2$ elements are $\{-1, 0\}, \{-1, 1\}, \{0, 1\}$.
The subset of $A$ having $3$ elements is $\{-1, 0, 1\}$.
Thus,all the subsets of $A$ are $\phi, \{-1\}, \{0\}, \{1\}, \{-1, 0\}, \{-1, 1\}, \{0, 1\}, \{-1, 0, 1\}$.
