Math & Science ⇒ Can't compile subscript, superscript, etc.

[Aslund]

Hey everyone

Today I needed to do an subscript, but I got an compiler error, as I continued to test, I also noticed that Greek symbols also gave compiler error.

I get the following error:
--------------------------------------------------------------------------------
! Missing $ inserted.

I've inserted a begin-math/end-math symbol since I think
you left one out. Proceed, with fingers crossed.

LaTeX Warning: Command \o invalid in math mode on input line 246.

! Missing $ inserted.
<inserted text>

l.247

I've inserted a begin-math/end-math symbol since I think
you left one out. Proceed, with fingers crossed.
---------------------------------------------------------------------------------

When I look at the document, the symbols are there, but the linie after the command is in italic.
Does anyone know what to do to make it work?

Thanks alot for your help.

Hi,

please post the offending code, following the rules to build a minimal working example.

Commands such as \Delta for Greek letters, or ^ for superscripts or _ for subscripts are only valid in math mode.

To enter math mode in the middle of a paragraph, enclose the portion in the signs $...$.

So, for example, $\Delta$ should produce a Delta.

For superscripts or subscripts, use \textsuperscript or \textsubscript, unless you're writing something in mathematical or similar notation, and then enter math mode and use _ or ^.

Basics such as these are covered in introductory LaTeX materials such as lshort. If you're new to LaTeX, I recommend reading something like that.

As an addition to the document mentioned by frabjous you should take a look at "The Unofficial LaTeX2e Reference Manual". I recommend also to refer to our list with useful links for beginners [1]. That will help you to get along with such basics.
