  • notation - What does := mean? - Mathematics Stack Exchange
    I have seen variants of these used by people who predate widespread knowledge of computer programming It would be interesting to know the earliest uses of a special symbol for this (and what symbols were chosen) An advantage of $:=$ is that it has a partner, $=:$, allowing it to distinguish which side is equal to the other by definition
  • Difference between ≈, ≃, and ≅ - Mathematics Stack Exchange
    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
  • A Guide to Every Symbol in MTG (yes, really) : r magicTCG - Reddit
    With the mana symbol that appears on Mox Lotus and Urza's Fun House, {∞}, that one is indeed a symbol, but it's covered under generic mana, where they mention that it can be any number And yes, I know that infinity is not a number in the mathematical sense, but it is a number as far as silver-bordered Magic rules are concerned
  • notation - What does ∈ mean? - Mathematics Stack Exchange
    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"

  • Is there a mathematical sign for or? - Mathematics Stack Exchange
    The logical "or" is $\vee$; however, unless you are doing mathematical logic like set theory, that symbol is not widely used, because it is usually unnecessary and the work required to understand it outweighs its potential use time saving
  • Does not necessarily equal symbol - Mathematics Stack Exchange
    Note, IF you do such a thing, make SURE that the expression and it's symbol is LOGICAL, WELL NAMED, and EXPLAINED, and post the symbol with name and explanation the correct instance: How to propose new notation, which I do not have to say to you, but just to be sure, to be on the safe side, I will do this either way If only because one, though
  • adding more symbols to the toolbox : r Revu - Reddit
    You could also create new symbols using your markup tools and then save them to your symbol toolbox by using the right click and adding to toolbox If you like their symbols but want to slightly edit you could use the symbol, modify it with markups, and then group and save as a new symbol
  • How to get the glitched text? : r Minecraft - Reddit
    So you know the text in the end cutscene thing? Like the glitchy lookin text? I heard there was a way to get items to be named that form of text So I'm just wondering how to do that in Java, because you can't seem to paste the symbol or use the alt shortcut in the game
