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

\({(p-1)}^p \equiv -1 \pmod {p^2}\)

\(\equiv {p^2-1} \pmod {p^2}\)

\(\equiv {(p-1)(p+1)} \pmod {p^2}\)

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?

Log in to reply

@zico quintina Like this?

\(\begin{align} (p-1)^p & \equiv -1 \pmod {p^2} \\ & \equiv p^2 -1 \pmod {p^2} \\ & \equiv (p-1)(p+1) \pmod {p^2} \\ \end{align}\)

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 \(\not{147}\), 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!
