TITLE: ⋇ "Division Times" operator in Unicode (U+22C7)?
QUESTION [6 upvotes]: I found this maths operator in Unicode:
⋇
It is called "Division Times" (U+22C7).
Does it behave like ±? For example: 3 ± 2 means it is an ∈ {1, 5}. So 3 ⋇ 2 means it is an ∈ {1.5, 6}?

REPLY [10 votes]: The intent  ought to be what you said. So, it is  $a ⋇ b$ is short for "$a \ b$ or $a \ b^{-1}$" that is the multiplicative analogue of $\pm$. 
Yet, a more common way to write $a ⋇ b$ is just $a \  b^{\pm 1}$.
In addition, I never heard of this operator, all the early search hits are for Unicode-tables not math, and at least to me it looks quite similar to an asterisks at small font size.
In short, it seems more like an artifact of getting a symbol-set somehow 'complete.' Rather than something that is actually used. 
That said, I just learned that there is a LaTeX (needs amssymb) and also MatjJax command for it,  it is \divideontimes giving $\divideontimes$
