One aspect about being a mathematician in a physics class, is that people will say something nebulous like radians are a unit less and in the back of my head I have to be like no it’s actually meter per meter. But I’m not allowed to say that

{Expression : Rule}
{Rule : Expression}
{Expression : Rule} is the form of{2n : n ∈ ℕ} and is formally expressed as “the set of all thing of the form 2n such that n is an element of ℕ”.
{Rule : Expression} is the form {n ∈ ℕ: 2n} and is formally expressed as “the set of all n in ℕ such that 2n”
Such that?

So I was talking about adding dissimilar matrices together: think 3 × 3 and 4 × 2. And it occurred to me that the main problem with those things is that ultimately we assumed the matrixes to represent the same space and not different spaces. For instance ℝ^3 is not necessarily a subset of ℝ^4. It could even be true that ℝ^4 ∩ ℝ^3 = ø.
I don’t think is a problem created by a closed operation as that’s my usual approach to generalizing problems, but I think this approach could be useful. More research needed.
While working in combinatorics I noticed that we don’t have a word(seamingly) for a object where order doesn’t matter. I suggest “ordn’t”
