A line that begins with a variable can look clumsy even if the variable is not at the
end of a phrase.
The remaining values are irreducible, in which case it is clear that set
D
is not empty.
Nor should you let a quantity become detached from its unit.

Most word processors provide an unbreakable-space character that prevents this
behaviour. However, some word processors insist on breaking lines at awkward
places in mathematical expressions.
In this case the problem can be simplified by using the term
f
(
x
1
,...,
x
n
)
as a descriptor.
Sometimes the only solution is to rewrite the surrounding text.

Numbers
General writing guides recommend that large numbers should be written out in
digits, such as 1
401 or 23, and that small numbers or round numbers should be
spelt out: “one” rather than 1, and “a hundred” or “one hundred” rather than 100.
In technical writing, however, digits are generally preferred when quantities are
being reported, and in particular when numbers are being compared. First, digits
are easier to locate when scanning a text, as a reader may do to remind themselves
of numerical results reported earlier. Second, varying the presentation for figures
that are meant to be compared introduces a false and perhaps misleading distinction
between them.
However, words are sometimes preferable, for approximate numbers and for num-
bers at the start of a sentence, although, as noted earlier, it is generally better to recast
the sentence so that the number is elsewhere. Percentages should always be in figures.
