Ok thanks Ginger, and thanks guest too :)

Hi Jonathana

Thanks Ginger  

Please post one question at a time and learn from the answer before you post the next question.

Hi Guest,

What do you think the answer might be?

One of your class or group members already asked this question

Ths abuse that happens on this site also frustrates me and I'd like to see far less full answers.

Howerver, there are some students here that are definitely learning from the answerers expertise.

Should they be denied access to a site like this becasue others abuse what the site offers.

If I was still actively teaching in a classroom I have no idea how I would cope with sites like this one.

They would frustrate the h**l out of me.  I guess I would just have to accept that they facilitate learning and/or they facilitate cheating. KnockOut is right in that a students will always find ways to cheat. It is largely up to them how they use or abuse available resources.

But the fact that sites like this exists means that controlled exams are more vital than ever!

Interpreting Rom's answer:

If you ask a proper question you might get a proper answer.

Otherwise you get a bad joke, or worse.  :D

Here is a way I personally like better

\(9/1-7/11 \\ = 9-7/11\\ =8+1-7/11\\ =8 \frac{4}{11}\)

Thanks Chris :)
