I'm typing in LaTeX on a Linux machine (Ubuntu) using Emacs (for typing and compiling). If I type (in mathematical environment)

\left\{blah blah\right\}

I don't see any brackets at all.

If I type

\{ blah blah \}

the brackets are not scaled.

How can I fix this?


It must have been mistype or something, now everything works...

This question is unlikely to help any future visitors; it is only relevant to a small geographic area, a specific moment in time, or an extraordinarily narrow situation that is not generally applicable to the worldwide audience of the internet.

@Martin Scharrer Why did you add the backslash? Maybe this caused his problem. – Thorsten May 8 '11 at 10:00
@Thorsten: The backslash was there already in the code, just not shown. I simply added white lines so the code blocks are formatted right. The edit diff doesn't show that correctly. You need to view the source code to see it. – Martin Scharrer May 8 '11 at 10:03
@Martin Scharrer Oh, I didn't know that. I need to keep this in mind for the future. – Thorsten May 8 '11 at 10:05
@Yotam Since you have some responses below that seem to answer your question, please consider marking one of them as ‘Accepted’ by clicking on the tickmark below their vote count.

@Thorsten: Thanks for trying to help around here, but that comment should be added only after quite some time (2 days or so in my opinion), but not after 6 hours. Normally it is a good thing to wait a day before accepting an answer, so that other have the chance to give an (maybe even better) answer. – Martin Scharrer May 8 '11 at 16:04

Try using them like this:


You have to use them in mathmode and put a backslash in front of the bracket.

when you compile the following example you will get the error

Missing $ inserted \left

The example:

\left\{blah blah \right\}

You see the error is clear.

$\left\{\mbox{blah blah}\right\}$ %without amsmath

$\left\{\text{blah blah}\right\}$ %with amsmath

Please create a minimal example. It is easier for use.
