Inverse matrix order of operation
Yes. If you're compounding operations to make a matrix, then the inverse matrix will be the compound of the inverse operations, in the reverse order. So if $C = AB$ then $C^{-1} = B^{-1}A^{-1}$

Think of it geometrically. Taking a 2D example, if you have an object at the origin, and you want to move it +2 units in X then rotate around the origin by +45 degrees. To undo this transformation, you need to first rotate by -45 degrees then translate by -2 units in X.
