    The other use is as a door-opener; Learning these maths fundamentals enables you to pursue a stem degree

      as a door-opener

      You say that but they still need to teach you the “why”. For example I did A-level maths which was a door to learning discrete maths in uni. Matrices, graphs, etc.

      In 20yrs as a software dev I never used any of it. Only needed basic arithmetic.

      To this day I’ve got no bloody clue what the point of matrices are.

        I used them in computer graphics and game programming. As a regular software dev, not so much.

        They’re used for manipulating vectors.
        Just like how in
        v
        the a makes the vector v longer or shorter, in
        v
        M can change the vector, for example rotate it.

        Just like vectors and other mathematical objects, matrices are purely theoretical concepts. There is no direct real-life meaning to them.
        However, there are a bunch of real-world problems where matrices can be put to use to calculate something meaningful.
