How can I type the "isomorphic","not equal" and "the set of integers , rationals and reals" symbol ?
What is the code ?
$=$ means equal, how to write "not equal"
What about real numbers, rationals, natural numbers and integers?

$\cong$ for $\cong$
$\ne$ for $\ne$
$\mathbb{R}$, $\mathbb{Q}$, and $\mathbb{Z}$ for $\mathbb{R}$, $\mathbb{Q}$, and $\mathbb{Z}$, respectfully.
