List all the subsets of the set $\{-1,0,1\}.$
List all the subsets of the set $\{-1,0,1\}.$
Let $A=\{-1,0,1\} .$ The subset of $A$ having no element is the empty set $\phi .$
The subsets of $A$ having one element are $\{-1\},\{0\},\{1\} .$
The subsets of $A$ having two elements are $\{-1,0\},\{-1,1\},\{0,1\} .$
The subset of $A$ having three elements of $A$ is $A$ itself.
So, all the subsets of $A$ are $\phi,\{-1\},\{0\},\{1\},\{-1,0\},\{-1,1\}$ $\{0,1\}$ and $\{-1,0,1\}.$
