WebMathematics. A backslash-like symbol is used for the set difference. The backslash is also sometimes used to denote the right coset space. Especially when describing computer algorithms, it is common to define backslash so that a\b is equivalent to ⌊ a/b ⌋. [citation needed] This is integer division that rounds down, not towards zero.

Web17 Apr 2011 · If X is an abelian monoid (i.e., has a subtraction operation) then X-A could be the set of all elements of X which can be expressed as difference of elements of X and A. But I can't say that's a very popular usage. I would be reluctant to use the minus sign when \setminus is available. – Web25 Dec 2014 · The backward slash is kind of the set theory equivalent of subtracting, i.e., A ∖ B = { a ∈ A ∣ a ∉ B }. Use \setminus to get the set difference operator, and \mid to get the vertical bar with space around it. But keep in mind that you still can get something like Q ∖ … gold coast smash repairs burleigh heads
