I agree that formulas are necessary for things like signal processing systems, even the dynamic difficulty adjustment, with its derivatives and integrals needs some calculus notation.

But all the set theory, especially, it is not intuitive what A, B, C, F M or whatever letter you use refers to. You have to memorise a code to read it, which means that this notation is essentially encrypted.

All of it much more easily understood in venn diagrams and other visuals. And words can describe it really well too, even more compactly, but without that encryption. It's always the set theory stuff that is the most sleep inducing for me. And the more complicated calculus is beyond my highschool training, yet I can still write the algorithm for it if it's broken down into a linear set of operations.
