I tried to use the command \mathbb {R} in order to get the set of real numbers symbol in LaTeX. But, I just simply get the normal R.

How can I represent the set of real numbers in LaTeX?

    Please stop using the [tag:tex-core] tag for all your questions, it hasn't been appropriate for any of them I think. – Torbjørn T. Dec 11 '13 at 10:03

    It seems pointless to say it again but your question should include a complete small document that shows the problem. \mathbb{R} should either produce a double struck R or an error message, if it does not there is an error in code you have not shown. Please edit your question to include sufficient information that it may be answered. – David Carlisle Dec 11 '13 at 10:05
  • @ Ian Thompson. Thanks a lot. That worked... – Simplicity Dec 11 '13 at 10:07
  • @Torbjørn T. Thanks for your note. What tags do you recommend? For instance, to this question let's say – Simplicity Dec 11 '13 at 10:08

    @Simplicity so your question was totally misleading, \mathbb did not generate a normal R it generated an error – David Carlisle Dec 11 '13 at 10:08
  • @DavidCarlisle --- I think some IDEs have an option to run in nonstop mode by default, in which case you do get a normal R. This is one reason I consider IDEs to be the work of Satan. – Ian Thompson Dec 11 '13 at 10:12
  • @IanThompson: But all IDEs show a list of errors after compiling. But there are users who ignore them and think the document is fine as long a PDF comes out … – Tobi Dec 11 '13 at 11:16
