Custom tabulation in enumeration

I want to make a simple document with some exercises and I need to make a list. What I expected is something like MS Word, with a tabulation at left. But I get this:

LyX:

PDF:

I want to get something like this (with numbers and characters):

I mean when I put a list with numbers or bullets, they're aligned at left and not with some space (or tabulation) to be into the paragraph.

So, what I mean, how can I solve it?

I'm using the latest version of LyX and MiKTeX, and Windows (I guess it's the same for GNU/Linux).

• I don't really understand your question. The first two images show the LyX input and PDF output. They match, so the output is "as expected". Now you mention that instead you want a list with bullets (in the picture), or is it numbers (in the text)? – Werner Nov 21 '14 at 17:44
• I want to get the same align at left with numbers and bullets (the last image is from my Calculus profesor's excercises pdf). – captainepoch Nov 21 '14 at 17:45
• Now you're talking about alignment, while I was asking about the numbering of the items. Two completely different things. Do you know how to insert a bulleted list in LyX? – Werner Nov 21 '14 at 17:47
• I think you don't really understand what I want. If I put a number list, I get a list which is not aligned as I want (last image, but with numbers instead of bullets). And the same thing happens when I use bullets. – captainepoch Nov 21 '14 at 17:48
• If I don't understand it, many others might also not. You should explain yourself better in the question. – Werner Nov 21 '14 at 17:49

If you want to remove all of the regular paragraph indentations, then add \setlength{\parindent}{0pt} to you Document > Settings... > LaTeX Preamble. If you want to selectively remove the indentation of a specific paragraph, place your cursor in the paragraph and follow Edit > Paragraph Settings... and uncheck "Indent Paragraph":
This would be equivalent to inserting \noindent in an ERT as part of the paragraph text.
