Below an example that defines a numbered environment called example :. In this L a T e X snippet the new environment example is defined, this environment has 3 counting-specific commands.

    For further information on user-defined environments see the article about defining new environments. For example if you want to change the way a subsection counter is printed to include the current section in italics and the current subsection in uppercase Roman numbers, you could do the following:. Default counters in L a T e X.

    If you want the NewCounterName counter to be reset to zero every time that another OtherCounterName counter is increased, use:. Subsection e.

    Insights Author. Gold Member. Last edited by a moderator: May 4, I had been meaning to get around to learning this, and it works very well. Thanks robphy and Fenn for replying. When I wrote for example Code:. That might be a little confusing to the reader, where the depth of equation indices depends on the section where the equation resides.

    It may not be obvious to the reader whether 1. Just my opinion though.L a T e X supports this type of organization and also customization of the sectioning and numbering. Commands to organize a document vary depending on the document type, the simplest form of organization is the sectioning, available in all formats.

    Section numbering is automatic and can be disabled.

    Open an example in Overleaf. L a T e X can organize, number, and index chapters and sections of document. There are up to 7 levels of depth for defining sections depending on the document class:.

    To get an unnumbered chapter, section, sub-section, etc. These will not go into the table of contents. See the article Table of contents for an example and description of this command. Below you can see an example:.

    Books are the most complex type of documents when it comes to grouping the content in sections. Below a complete example with parts, chapters, sections and subsections. You can use the titlesec package to customize chapters, sections and subsections style in an easy way. Open an example of the titlesec package in Overleaf. No Search Results. Sections and chapters.

Praesent imperdiet mi necante This file.If you need to insert cross-references to numbered elements in the document, like equations, sections and figures there are commands to automate it in L a T e X.

    This article explains how. Open an example in Overleaf. This also works on chapters, subsections and subsubsections.

    See Sections and chapters. At the introduction an example of a image referenced was shown, below cross referencing equations is presented. Elements usually are referenced by a number assigned to them, but if you need to, you can insert the page where they appear. In the example above the equation 1.

    This command can be used with all other numbered elements mentioned in this article. On Overleaf cross references work immediately, but for cross references to work properly in your local L a T e X distribution you must compile your document twice.

    There's also a command that can automatically do the job for all the references to work. For instance, if your document is saved as main. To change the output format use -dvi or -ps. No Search Results. Cross referencing sections and equations. This section will be later referenced.In LaTeX, you can easily reference almost anything that can be numbered, and have LaTeX automatically updating the numbering for you whenever necessary.

    The objects which can be referenced include chapters, sections, subsections, footnotes, theorems, equations, figures and tables [1]. The commands to be used do not depend on what you are referencing, and they are:. LaTeX will calculate the right numbering for the objects in the document; the marker you have used to label the object will not be shown anywhere in the document.

    If you reference a marker that does not exist, the compilation of the document will be successful but LaTeX will return a warning:. Because of that, you would have to compile your document twice to see the output with the proper numbering.

    If you only compile it once, then LaTeX will use the older information collected in previous compilations which might be outdatedand the compiler will inform you by printing the following message at the end of the compilation:. You could write something like:. Since you can use exactly the same commands to reference almost anything, you might get a bit confused after you have introduced a lot of references.

    It is common practice among LaTeX users to add a few letters to the label to describe what you are referencing. Some packages, such as fancyrefrely on this meta information. Here is an example:. Another suggestion: try to avoid using numbers within labels. You are better off describing what the object is about.

    This way, if you change the order of the objects, you will not have to rename all your labels and their references. If you want to be able to see the markers you are using in the output document as well, you can use the showkeys package; this can become very useful as you develop your document.

    For more information see the Packages section.

    Here are some practical examples, but you will notice that they are all the same because they all use the same commands. You could place the label anywhere in the section; however, in order to avoid confusion, it is better to place it immediately after the beginning of the section. Note how the marker starts with sec:as suggested before. When declared outside, it will give the section number.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

    But I need it to show me only the numbers of the subsection and the theorem, but not the section number, like this:. I don't understand why you want this particular theorem numbering system, but the code does what you want:. There's no easy way to do this. The AMS Theorem Package only provides a way to control when numbering resets section, subsectionif it's tied to other environments corollary, lemma and number order "1. See these LaTeX tips.

    Cross referencing sections and equations

    This will reset the numbering command of the thm environment to ignore the section numbers when numbering theorems and display only the subsection numbers and theorem numbers. Section numbers will still be displayed in front of section headings, just not the theorems included within the sections. So, just as you describe, the first theorem in the second subsection of the first section will be numbered 2.

But I need it to show me only the numbers of the subsection and the theorem, but not the section number, like this: Theorem 2.

    Please don't do this. As a frequent reader of mathematical books, I hate it when books use this numbering style. If you do this, saying "Theorem 3. I'm a decade late in responding to kquinn but I really have never found this to be ambiguous. Saying "Theorem 3. To refer to another chapter authors will say "Theorem 3.
