Transpose
Flipping a matrix so its rows become columns.
Picture a spreadsheet with 2 rows and 3 columns. Now rotate it so the first row becomes the first column, the second row becomes the second column, and so on. That flip is the transpose. A 2 × 3 table becomes 3 × 2.

A matrix moves the grid. Its inverse moves it back. Try a matrix whose square collapses to a line: area 0 means nothing can undo it.
