Additionally, the subsequent columns contains an informal explanation, a. The following table lists many common symbols, together with their name, how they should be read out loud, and the related field of mathematics. For example, the hyphen key -produces the minus sign (). In logic, a set of symbols is commonly used to express logical representation. Some keys produce a mathematical symbol similar to the character they produce on US keyboards. While this is a serious limitation, multi-level formulas are not always needed and even when they are needed, proper math symbols still look better than improvised ASCII approximations. So, for their sake, I have decided to share this answer. Most keys have their normal meanings as in US keyboards, when used as such or with the Shift key. So, try it The List shows just the values (number) you have to press ALT key and then these numbers on Keyboard. List of commonly used symbols with values is given here. Here’s a simple way to write any symbol using shortcut keys, i.e. I know this question is over $5$ years old, but for people who search on Google, "what does 'such that' mean?", this post is one of the first links to come up. This trick is however not possible in Notepad files.
You can find answers and comments related to that latter symbol $\varepsilon$ in the linked posts.
The following mathematical symbol sets are available in the Symbols group in Word. Click the symbol that you want to insert. Click the arrow next to the name of the symbol set, and then select the symbol set that you want to display. A better, but less common, notation is $\varepsilon$ (formatted with $\varepsilon$). Under Equation Tools, on the Design tab, in the Symbols group, click the More arrow.
I would use \st since it stands for such that, but you can use any new command you like.Īlso, I have seen $\$$ be used to denote such that (because it kind of looks like $S$ and $T$ put together, which is kinda cool), but if you ever need to user super-factorials, I do not suggest this notation. $$a\in \left\ and whatever the command \ $\ldots$ is, that is now your new (and hopefully easier) command to create this symbol.
