Relation symbols in LaTeX math
In math mode, use \leq (or \le) for ≤, \neq (or \ne) for ≠ and \in for ∈; most relations have a negated form with an n in front, such as \nleq, or with \not before the symbol.
Using relations
A relation compares two things, and LaTeX puts a thick space on each side, a little more than around an operator. Typed <, > and = are relations already; the others have commands.
Relations in running text
For all $n \geq 44$ we have $a_n \leq b_n$, so $\lim a_n \neq \infty$.
The set satisfies $x \in A \subseteq B$, and $\pi \approx 3.14$.Many relations come in a negated form. Where a command exists, such as \neq, \notin, \nleq or \nsubseteq, use it: the slash is drawn to fit. \not in front of any other relation strikes it through.
Negated relations
a \neq b \qquad x \notin A \qquad p \nmid q \qquad A \nsubseteq B \qquad x \not\equiv yDefinitions often use :=. With mathtools, \coloneqq gives a colon centred on the equals sign, which reads better than typing :=.
Definitions and equivalences
f(x) \coloneqq x^2 + 44 \qquad a \equiv b \pmod{n} \qquad A \cong B \qquad x \propto yAll relation symbols

Questions and answers
What is the difference between \le and \leq?
None. \le and \leq are two names for ≤, and \ge and \geq for ≥. \leqslant and \geqslant from amssymb give the slanted form.
How do I write "not an element of" in LaTeX?
Use \notin: $x \notin A$ gives x ∉ A. \not\in also works, but \notin is drawn better.
How do I write "approximately equal" in LaTeX?
\approx gives ≈. For "similar" use \sim (∼), and for "asymptotically equal" \simeq (≃).
