I have found some pretty complete lists (I think) of mathematical symbols here and here, but I don't see a symbol for the word "and" on either list. A person could easily just write the word "and" or use an ampersand, but I was wondering if there …

In my opinion the less often a symbol is used where a few words can go, the better. That said, there are many places where symbols are useful and simplify matters. The word "where" can often be replaced with "such that", and corresponding to this we …

The symbol ≅ is used for isomorphism of objects of a category, and in particular for isomorphism of categories (which are objects of CAT). The symbol ≃ is used for equivalence of categories. At least, this is the convention used in this book and by most category theorists, although it is far from universal in mathematics at large.

2014年11月3日 · $\begingroup$ @DavidRicherby Although I myself tend to not overuse notation, I simply shown the most fitting "symbol" for the deduction that's been proposed by the OP. I'm sure that it's easier to understand using words, but I …

what does ∇ (upside down triangle) symbol mean in this problem. Ask Question Asked 14 years, 4 months ago.

2019年1月5日 · $\wedge$ is (most often) the mathematical symbol for logical conjunction, which is equivalent to the AND operator you're used to. Similarly $\vee$ is (most often) logical disjunction , which would be equivalent to the OR operator.

2014年6月25日 · Another possible notation for the same relation is {\displaystyle A\ni x,} A\ni x, meaning "A contains x", though it is used less often. The negation of set membership is denoted by the symbol "∉". Writing {\displaystyle x\notin A} x\notin A means that "x is not an element of A".

2016年12月13日 · What is the symbol for the range of the numbers? i.e. the lowest-highest number in the set. For example, the min max is $1-5$. The ____ is $1-5$. (insert math symbol into blank). Should such a beast exist, I'd be particularly interested in it's unicode character...

2011年3月18日 · $\begingroup$ I was aware of Pascal using :=, but not the others.I think it is possible that the language designers of that time where influenced by maths (as has happened a number of times), but := is so far the only easily typable symbol mentioned here, so it is perfectly reasonable to assume it stems from programming languages in the first place.
