If this appears in an exam simply write DNE for Does Not Exist, there are other ways to write this but that is the most common way...

Very nice, MathsIsFun... you never cease to amaze me!

If only Maths Is Fun existed many years ago when I began learning about trigonometry. The way you explain things with such simplicity would have been so helpful. sad

Ni hao means hello, adding 'ma' to the end makes it 'how are you doing today?'.

I don't think he got the chemistry kit he wanted this year.

Meh, language... it is a concept that would be much simpler if anyone applied themselves to the same rule

Nice page. ^_^

The link appears to be dead at the moment...

For Reaction Math, you have a highscore table (which is currently faulty) - you can use that for all your challenging needs! ;D

I think the answer pattern follows a sequence. I am currently investigating it now, it seems there is a pattern!

MathsIsFun also has something just like this. Search for "Reaction Math", it will probably keep you entertained for a long time!

What on earth happened to the Guestbook? I remember there used to be dozens of messages per day in here! Now I see barely any messages in a month ...

On closer inspection I think this is some sort of remix of Pachelbel's Canon in C#. Seems very odd to base a remix on that as I have never encountered a Canon with a note sharped or flattened.

Yeah. And in the Quarter-Final, Febregas really helped by scoring that winning penalty. In one moment, he got sent Buffon going the wrong way, the ball going right into the perfect spot in the net, sent the fans in an uproar, alarmed the Prince of Spain and got them through to the Semi Final! And the best part of it was, that was the first time he had actually taken a penalty. No wonder he was muttering subtle prayers and kissing the ball! You know what they say - you can always rely on a gunner to score a penalty. Lucky they kept all their best penalty shooters on, though. I'm also glad that it didn't go to penalties for the final, otherwise Germany would have either mauled them or broken their chain record of never missing a single penalty since 1982. Honestly, I have to say ... this Euro 2008 tournament has been completely unbelievable. Not once did I think the underdogs - Turkey, Russia - would all make it to the Semi Final! And to be honest, Turkey and Germany are quite evenly matched. Germany were lucky to score their third goal to make it 3-2 in the ninety-first minute. A brilliant tournament, and it really has made me look forward to the upcoming tournament - the big one - the UEFA World Cup 2010. I can't wait ... !

Well, it's lucky that it didn't go to penalties. Germany have never missed a penalty shot since the 1982 World Cup. They are by far the best team at taking penalties ever to have existed.

Looks interesting ... I'll check out the URL you gave me, see if this game turns out to be any good.

Reminds me of SuDoKrazy ...

I came across the method of differences for the first time today. It's fantastic.

That is all smile

Of course - Maths Is Fun!

Same. big_smile

Final was a bit boring. Honestly, if Spain hadn't made so many silly mistakes, then they could have easily made it 3-0, 4-0, 5-0 or perhaps even 6-0.

All teams have their rise and fall - it looks like Germany have finally fallen, and there's a new titan in town.

I’m not really against the differences between BE and AE spellings. I use the spelling COLOUR but I have no objection to other people using the spelling COLOR (being the open-minded person that I am roll).

I am less tolerant of lazy idiots who type “u” for “you”. mad

Not to mention the annoying but now unfortunately all too widespread dropping of apostrophes (e.g. DONT instead of DON’T, etc). swear

ur right u no smile

Italy played way too much like Greece in Euro '04. -_-

Spain win! They will now face Russia in the Semi-Final ...

Fabregas is a hero! Especially the goalkeeper ... wonderful saves he made. Wasn't Buffon's day, I suppose.
