Today's beef with math: overloading the term "inverse". Inverse of a scalar: 1/n, aka n^-1 Inverse of a matrix: m^-1. So far so good. Inverse of vector: -v. What. Why not v^-1? Turns out both would be right. There is Additive and Multiplicative Inverses.
Of course we have the term "reciprocal" that also means Multiplicative Inverse. The bigger issue to me is when math libraries implement inverse(vector) as additive and inverse(matrix) as multiplicative. No consistency.
Moreover, vec*vec is element-wise, but mat*mat is not. But mat+mat *is* element-wise. Not infuriating at all. Hot take: At least for computer science, all basic math operators should be element-wise. Anything else should be a function. Dot, cross, transform, etc.
