- Symbol for “such that” (not in set) - Mathematics Stack Exchange
Nobody should be using ∋ ∋ to mean "such that"; it is used in texts everywhere to mean ∈ ∈ but in the reverse direction (that's why the LaTeX code is "\ni" after all) I would argue ":" is the superior notation for set-building since (in most handwriting) it is the least likely to be confused with anything else (I, l, 1), hence being the most readable
- notation - What does := mean? - Mathematics Stack Exchange
It's one common notation for stating that the left-hand side is defined as (in contrast to equal to) the expression on the right-hand side
- notation - What does versus mean in the context of a graph . . .
I would agree with the rule " [dependent] versus [independent] " The word "versus" can mean "compared with," and it more frequently makes sense to compare a dependent value with its associated independent value, because well, the independent variable doesn't really "care" about the existence of the dependent variable, but the converse relationship is by definition

- notation - What does ∈ mean? - Mathematics Stack Exchange
I have started seeing the "∈" symbol in math What exactly does it mean? I have tried googling it but google takes the symbol out of the search
- notation - The best symbol for non-negative integers? - Mathematics . . .
The set of natural numbers {0, 1, 2, …} {0, 1, 2,} is often denoted by ω ω There are two caveats about this notation: It is not commonly used outside of set theory, and it might not be recognised by non-set-theorists In "everyday mathematics", the symbol N N is rarely used to refer to a specific model of the natural numbers
- notation - Difference between ≈, ≃, and ≅ - Mathematics Stack . . .
In mathematical notation, what are the usage differences between the various approximately-equal signs "≈", "≃", and "≅"? The Unicode standard lists all of them inside the Mathematical Operators Block
- notation - Symbol for elementwise multiplication of vectors . . .
No, I would be concerned about ⊗ ⊗ causing confusion with the outer product (although the outer product will produce a matrix, and the componentwise product will produce a vector, so if the context is clear enough perhaps this will not be a problem) I recommend writing componentwise multiplication of vectors using some symbol that does not have a standard meaning, perhaps ⋆ ⋆ (\star
