#Matrices are as confusing as the movie Matrix

Is it just me, or is matrix multiplication extremely unintuitive? Especially the inverse forms etc.

They are unintuitive if you’re coming at them as formulas that were written down with no real reason behind them. But they come from somewhere. They are encoding linear maps, and matrix multiplication encoded composition of function. The matrix inverse corresponds to the inverse function.

Lots of things have simple descriptions that lead to complicated formulas. If you want to have an intuition about them, you need to think about concepts and only worry about the formulas when you need to do actual computations.
