Can someone maybe help me out and let me know how to set:  ≠   in LaTeX? I am using Overleaf. I have tried \≠  but it did not work out.  Thanks in advance. Greetings.

I know what my symbol or character looks like, but I don't know what the command is or which math alphabet it came from. How do I go about finding this out?

I use LaTeX to take quick notes about my programming work.  I have a couple of frustrations:    I need to use underscore a lot because of variables named with underscores.  However, I have to escape each one of them "\_", thus making my notes less readable on the markup side. I commonly want to use "&lt;" and "&gt;" symbols - why oh why are the default representations of these symbols "¿" and "¡"?   Is there anyway I can alter LaTeX so that "_", "&lt;", and ">" literally typeset as "_", "&lt;", and ">"?

In LaTeX align, I'm struggling to align polynomial terms and assume there's an easy way to do it. But I cannot find the simple/elegant solution. What I would like is something like this:  x1 + x2 ______________ = 3  x1_______________+ x3  = 4  etc with more lines and variables (the underlines are just for space/alignment). Any help appreciated.  UPDATE Here is the solution I found:  \begin{alignat*}{7} 8x_1 &amp;{}+ 4x_2 &amp;{}+ y_1   &amp;        &amp;        &amp;        &amp;= 160     \\ 4x_1 &amp;{}+ 6x_2 &amp;          &amp;{}+ y_2 &amp;        &amp;        &amp;= 120     \\ x_1  &amp;         &amp;          &amp;        &amp;{}+ y_3 &amp;        &amp;= 34      \\ \phantom{{}+{}x_1}&amp;{}+x_2&amp;&amp;        &amp;        &amp;{}+ y_4 &amp;= 14      \\ x_1\geq0&amp;x_2\geq0&amp;y_1\geq0&amp;y_2\geq0&amp;y_3\geq0&amp; y_4\geq0 \end{alignat*}   with result:

I  there's a LaTeX package for printing the text of "lorem ipsum".  Surely then, there's also a macro / package for writing "LaTeX" (with the proper super-/subscript) in a document.  But I found googling for this a bit hard. ("LaTeX macro"? Probably not.)  Can any of you groks help me out here?

This is difficult for me to explain, but how do I put words over a symbol? For instance, I want to add words over an equal sign. Anyone know the command/syntax for that?  Also adding ^ doesn't cut it..., I want the text to appear ON TOP.

I have a LaTeX file for a book chapter, which may need to be converted to Word at some point, because that is what the publishers use (sigh). This article doesn't have any math in it, but I'm still using LaTeX, because even when not writing mathematics, it is better than the alternatives. Unfortunately, I'm making heavy use of characters that are only supposed to appear inside a math environment, notably the underscore character (_). I do use the math environment in a couple of places, but only very briefly.  So, my question is, can I tell LaTeX to make an exception for this specific character, and actually treat the underscore as a underscore? This would make later conversion to Word or some other word processing format easier. The alternative is to use \_ in lots of places. Bonus points if there is some way to still use underscore inside a math environment, not sure how that would work. To be clear, I'd like a general technique that would work with any of the special LaTex characters, though I suppose remapping most of the other ones would cause more trouble than it was worth.  I'm not sure what tags to use here, so please feel free to add. Thanks.  EDIT: It turns out this is a FAQ - .

all the LaTeX-tutorials tell me how LaTeX is an extention simplifying the building of TeX documents. Understandably, no one uses plain TeX anymore, right?  But I seem to learn better when I grasp the link between TeX and LaTeX. Does someone have a link to example files in plain TeX? I'd like to know which commands, macros etc. are LaTeX-specific.

Does anybody know how I can get exactly that symbol for the set of real numbers in LaTeX?   Additional image:    In this picture you have the symbol for the set of integers, real numbers and complex numbers. I think this must be a package.

Hi I am wondering what code is used to get text above the $\rightarrow$   have tried $ \xrightarrow{P}$ but not running on my LaTeX as I do not know which package to install or how to install it.   currently using \usepackage{mathtools} but it wants to load from a random directory and then LaTeX stops working.

I'd like to use LaTeX to typeset a novel. Could you recommend me any template?  What I mean is a template (some .tex file) where I can include my chapterN.tex files (mainly plain text) and get a pretty good design with zero work :)

In LaTeX, if I use \verb, how can I escape |? For example, I want to display ab|bc: \verb|ab[]bc|. What should replace []?

I want to write an equation in latex like the following one.   But I can not align a set of numbers with the coefficients completely. Here's my code:  \begin{equation} \begin{aligned} LNEP = &amp; -0.23LNEER &amp; +1.21LNCOST &amp; +1.50LNFD &amp; -1.03LNCP &amp; -9.44 \\ &amp; (0.12) &amp; (0.13) &amp; (0.27) &amp; (0.37) &amp; (1.33) \end{aligned} \end{equation}   And it looks like this:   Could somebody help me pls? Many thanks.

I just came over this syntax in some of the questions in this forum, but Google and any other searchengine tends to block out anything but letters and number in the search so it is impossible to search out "=>".  So can anyone tell me what it is and how it is used?

Mathematical operators, such as function names, should be set in roman type, not italics. Latex already has commands for some operators, including \max, \min, and \log.  How can I define additional such commands?

I'm pretty new to Latex, so please bare with me.  I'm trying to add this notation to my document:      I created the above picture from the , but it seems that when I try to apply the same code in my editor (TeXstudio), things are different...    For example, the above picture was produced using the code:    D=\left\{ x\in\mathbb{N}|1\leq x\leq 100 \right\}    But when I write it in my editor (enclosed in the $ sign of course), I get the following error when compiling:      Undefined control sequence. $D=\left{x\in \mathbb   The funny thing is that I was still able to see the output in the preview window (even though the editor shows that this line has error in it). That's the first problem.  The second problem is, although I can see the output in the preview window, it won't be the same as the output I get from the Online Latex Equation Editor. While the Online Latex Equation Editor produces this:      My TeXstudio editor produces this:     Notice the distinction in the N symbol that denotes the set of natural numbers. It is different the what I intended, which is the first version, as it produced by the Online Latex Equation Editor.   What's wrong here? Am I missing a package or something?

I'm new to TeX and tried to enter an equation using \mathbb. I received a prompt  LaTeX Error: \mathbb allowed only in math mode. See the LaTeX manual or LaTeX Companion for explanation.   I thought I would try here for an explanation.
