There was a web book I found a while ago that built up some sort of motivation for linear algebra. Unfortunately I don't remember what it was or the title. Edit: found it, https://graphicallinearalgebra.net https://graphicallinearalgebra.net Ymmv. Matrix multiplication is defined the way it is imo because it has interesting properties that way. Not very satisfying though.
