Sometimes, I want to have enumerate lists in LaTeX start at other than the first value (1, a, i, etc.) How can I make an enumerate list start at an arbitrary value?

9.77.2.2 How do I turn off equation auto numbering

https://tex.stackexchange.com/landing/r/digest?cta=question&id=2597

I have an equation like this: 
\begin{align} 
P(A \cup B) = \sum_{\omega \in A \cup B} P(\omega) = \sum_{\omega \in A} P(\omega) + \sum_{\omega \in B} P(\omega) 
= P(A) + P(B) 
\end{...

9.77.2.3 How to prevent LaTeX from hyphenating the entire document?

https://tex.stackexchange.com/landing/r/digest?cta=question&id=5036

I can't find where I can remove any kind of hyphenation and just have LaTeX just do a line break. 
edit: 
Honestly speaking I just don't like to read hyphenation anywhere and that's the only reason why ...

https://tex.stackexchange.com/landing/r/digest?cta=question&id=240868

The code I used to write 
is this one 
$$ 
X(m,n)= 
\begin{cases} 
x(n),\\ 
x(n-1)\\ 
x(n-1) 
\end{cases} 
$$ 
But I don't know how to write this one 
Also, what if I want to write this 
[math-mode] [cases]

9.77.2.5 Superscript outside math mode

https://tex.stackexchange.com/landing/r/digest?cta=question&id=47324

What is the easiest way to superscript text outside of math mode? 
For example, let's say I want to write the $n^{th}$ element, but without the math mode's automatic italicization of the th.  And what ...

When typing < or > in LaTeX and compiling with pdflatex, the less than and greater than symbols appear at upside down exclamation points. I'm not in math mode.

9.77.2.7 Displaying the binomial coefficient symbol in math mode

https://tex.stackexchange.com/landing/r/digest?cta=question&id=127707

The problem is caused by the symbol of binomial coefficient (symbol of Newton), often used in math: 
{N}\choose{k} 
In my document I have formula: 
$$ P(A) = \sum P(\{ (e_1,...,e_N) \})  =  {N}\choose{...
