Power set calculator
List every subset of a small finite set.
How to use this calculator
Replace the elements in PowerSet({1,2}); the result includes the empty set and the full set.
Tap the math below to edit it and see the result. Once a result is ready, press Tab on a hardware keyboard to accept it. Outside a matrix, Return completes the line; the phone math keyboard has the same Return action.

What to know
The number of subsets grows exponentially. The calculator displays at most 128 complete collection members.
Mathlean combines visual mathematical input with computation and canvas tools. Results depend on the expression and available engine support; check important answers independently.
