Question

I need to write something like NxN in LaTeX but I do not get how... How to do such thing?

Have a look at “How to look up a math symbol?” for ideas how you can easily find a particular symbol. — Caramdir, Apr 06 '11 at 16:07
You can try detexify, it's very valuable for me, I am also a LaTeX beginner. You just draw on it and it gives you the LaTeX command for the symbol. — Mobius Pizza, Mar 07 '12 at 14:20
If you want to reduce space between \times operator and its operands, you may use: $\medmuskip=0mu 3\times3$ within text, as outlined by http://tex.stackexchange.com/questions/41913/how-to-get-less-spacing-in-math-mode — math, Mar 16 '14 at 13:49

The x is done by \times. It must be used in mathmode:

$3\times4$

$N\times N$

Is there an equivalent for text mode? – Khalid Hussain Dec 07 '18 at 20:23

You can use \texttimes – Tomi Jan 04 '19 at 00:42
@KhalidHussain: In text mode just write $\times$ , but the numbers should be typeset in math mode as well, as it is done above in the answer post. – Martin Scharrer Jan 04 '19 at 07:53
@MartinScharrer how do you achieve the dot for multiplication sign instead of x? – Shimmy Weitzhandler Jan 14 '19 at 04:44

Answering to Shimmy's comment: you might be looking for \cdot. – Eerik Sven Puudist Apr 23 '20 at 12:11

$\times$ is not equivalent to \texttimes because the former will be set in the math font (as opposed to the main font). So if you're using a custom main font (and haven't bothered to set a matching math font) you may well prefer to use the text times. – Elliott Slaughter Feb 09 '21 at 23:37
