@Munem Sahariar Thanks for this guide,Really needed it
You could stylize LaTeX as LATEX
Log in to reply
Done!
how?
This guide is very helpful as I'm just learning to use LaTex, thank you.
I do have one question: is there a way to push lines slightly to the right (like the Tab feature in word processors) without pushing them all the way to the middle? For example, in the lines
(p−1)p≡−1(modp2)
≡p2−1(modp2)
≡(p−1)(p+1)(modp2)
I would really like to have the equivalence symbol in the second and third lines line up with the one in the first line. Is there a way to do that?

This one is my favourite:

There is another guide that was posted early. :)
In those latex codes, there is a typo. \sqrt[5]{4} appears as 54, not 34.

Is there a 'strikethrough' feature in LaTeX? I'm trying to show a a product of fractions with several factors in numerators and denominators cancelling each other out. So far all I've found is the \not feature, but this works very poorly; e.g. when I try \not{147}, I get 147, with only the 1 crossed out.
I would like to be able to cross out entire numbers; ideally, I'd also like to show either the strikethrough or the number (preferably not both) in a variety of colors.
Do you know whether this can be done? Thanks!

If the numerator and denominator of a fraction are two digit(or more digit) numbers then you have to use braces(Not necessary for single digit numbers). For example:
