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.
They’re used for manipulating vectors.
Just like how in
a×v
the a makes the vector v longer or shorter, in
M×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.
The other use is as a door-opener; Learning these maths fundamentals enables you to pursue a stem degree

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