LaTeX forum ⇒ Text Formatting ⇒ Aligning all equations to the left

[BigRedChess]

Hey Guys,

I'm trying to write a math paper, and I want every single equation in an align environment to be completely left aligned. However, when I tried "fleqn" or "flalign" it would just go a little bit to the left and still leave a lot of room between the margin. I also tried the set indent length thing after doing fleqn in the document class.

What else can I do?

I've attached all the information I thought was necessary.

Code: [Select all] [Expand/Collapse] [Download] (untitled.tex) Open in Overleaf

\documentclass[fleqn]{amsart}
 
\usepackage{fancyhdr}
\usepackage{graphicx, amssymb}
\graphicspath{ {./images/} }
\usepackage{enumerate}
\usepackage{amsmath}
\setlength{\mathindent}{-1cm} (I tried fiddling with this, and no cm length (whether it be -10, 10, or 0) changed anything)
\usepackage[parfill]{parskip}
\usepackage[export]{adjustbox}

Hi,

no need to use amsart, article together with amsmath would be fine as well. amsart is specifically for publishing in an AMS journal, it's focused to their needs.

Have a look at Left Alignment with Paragraphs for all Equations.

Hi,

I have written about 15 pages so far using the \begin{thm} and \begin{lem} environments that I assume come with the amsart document class. I am publishing this in a journal, so would say article be an acceptable document class? Would I have to change the "thm" and "lem" environments?

Thanks!

Hi John,

just load the amsthm package:

Code: [Select all] [Expand/Collapse] [Download] (untitled.tex) Open in Overleaf

\usepackage{amsthm}

Then you can define your theorems. All important amsmath functions are available for article and other classes as packages (amsmath, amsthm, amssymb, amscd, amstext, amsrefs, ...).

Just check if the journal already provides a style (class), that's very common. In that case you should use that style (with amsmath packages).

Sure - so I'm looking into the journal now but some other issues arise.

If I change from amsart to article, I get a lot of errors in these parts of my file:

\author{xxx}
\address{xxx}
\email{xxx}

\numberwithin{equation}{section} (this is for the newly stylized theorem and lemma environments

saying I have an undefined control sequence. Which document class can I use that will let me do the proper heading as well as having any kind of lemma/theorem/proof environment?

Thanks so much!

Jon

Did you include the amsthm package when changing the documentclass to article? An up to date MWE would definitely help here.

Here's the whole top attached (this uses a template that I found on Google)

I'm sorry, but this is not a complete MWE, it will not compile as it stands. And worse, you mention getting errors when changing the documentclass to article and this snippet uses amsart.

[BigRedChess]

Yes I must have incorrectly used the "amsart" template I found online. When I switch to article and use the given formatting edits I provided in my last post, it does not compile (though it does as of now). After a bit of tinkering here's everything in the top.

Like I mentioned before I just want to be able to force left align all equations for the paper.
