A -key- point that I make (repeatedly) is that mathematical
definitions/theorems etc. are -packed-: they're dense.
If you -analyze- them, i.e., break them up into their little pieces,
each of which you can understand individually
(which is not to say -in isolation-, but rather in a simpler context),
then the whole is much more tractible.
"Don't bite of more than you can chew:
 cut it up into bite-size chunks"

so when writing heavy statements/definitions/theorems,
put each concept on a line by itself.

-tables- and -lists- are under-used in math: sentences are easy to
write and typeset, but tables/lists are easier to parse -and-, b/c
they take up more space on the page, are conceptually "less dense":
you see that it should take a while to read, as it's a whole page
(or whatever).

EG:
"The Taylor Series of
 an analytic function
 converges
 uniformly
 on compact sets
 [to that function]"

$\forall \epsilon > 0$
$\exists \delta > 0$
s.t.
if $\abs{x-a}<\delta$
then $\abs{f(x)-f(a)}<\epsilon$
