That is a speciality of the Hungarian language: in many cases, when you use Plural in other languages, in Hungarian Singular is used, for instance after "elég".
But there are also other examples; in English you say "I do not have apples", in Hungarian "Nincs almám" instead of "Nincsenek almáim".
This especially applies for the so called "double organs" (hands, eyes, ears etc.), these are regarded as a single unit, hence we say "kék a szeme" [he/she has blue eyes]. A cyclops is "egyszemű" [one-eyed] because he had one eye ever since. But if a man loses one eye, then he is "félszemű" (literally "half-eyed").

I was wondering about the same thing.

Report it.

For me, as a native Hungarian speaker, "nem elég példát látsz" sounds a bit odd, but it is perfectly acceptable.
On the other hand, the standard order of the sentence constituents is (just like in English) Subject - Predicate (Verb) - Object.
But, unlike in English, if you put a sentence constituent before the Predicate, it gets a certain emphasis: I am painting a phone [while you are painting a door].
The same happens in your example: you put the Object ("elég példát") before the Predicate ("látsz"); whereas the suggested solution follows the standard order of sentence constituents.
