Well, most people who answer questions on WikiAnswers can spell correctly, but you must remember that this site is open to everyone and anyone who would like to contribute their knowledge free of charge.
Many people that answer questions here are children still at school and still learning how to spell. We cannot, and do not expect perfect spelling from them.
Also there are people who's first language is not English but who try very hard to write their answers in English. And of course we have people who are not literate in English for whatever reason, through disability or illness, and those who never learned.
By the way, American spelling of some English words can be different to the English way of spelling so this can make a difference depending on which version you use.
We do not want to be condescending in attitude towards any of our users for spelling mistakes as we welcome everyone from all walks of life who have something useful to contribute.
Everyone is encouraged to make corrections to spelling mistakes in answers, also when a supervisor finds or is notified that something is wrong on a question page they will make any necessary changes in grammar and spelling.
Yes,they can But some will not
If it is misspelled in an answer, then it is not WikiAnswers that misspelled it. WikiAnswers is a wiki, which means it has people answering questions, some of whom are good spellers and some of whom are not.
It can. Many people on WikiAnswers answer math questions.
That is the correct spelling, WikiAnswers, with a capital W and A.

At the moment you cannot add any spellings to the WikiAnswers spell-check dictionary.
Some people are lazy and some people just don't know how to spell and write correctly.

Perhaps for the same reason you cannot spell correctly.
