Maths Challenge 1

Yes. I forgot to tell everyone: I will put one Maths question and a Chemistry question every week. Suprised? Now, here is the question:

If a = 1990x+1989,b=1990x+1990,c=1990x+1991, find the value of a2+b2+c2-ab-ac-bc?

I hope you will count it and got correct answer. The answer will put on tomorrow.

Forgetfulness

Now, I should tell how forgetful I am. I can forget my things to anywhere and cannot remember it for a while. For example, I forget to take back my ez-link card for five times already. I also forget to give my girlfriend a present. The result is, she broke up with me(I was not very upset; she is not a very good girl at all). The worst is I forget to take bake my student pass, so I was force to sleep in my father's factory. It is very cold and smokey. So, I will have to change my habit if I don't want to sleep in factory.(Oh no, I remember that my book is in my class!)

Miss My Friend

I miss all my old friends. They are very good to me. But, it doesn't mean that my new friends do not help me. They help a lot. I heard that one of my old friends, who is good at chemistry, got 99 marks from one hundred marks! I still don't why he miss that precious one point. By the way, the two bloke who broke my electronic dictionary are talk to me now. Now, I only hope they will pay the repair fee.

In A Bad Mood

Do you all remember that two boys who ruined my electronic dictionary? They are not talking to me now. It seems like it was my fault when I "gave" my dictionary to them. One of them even tell their parents that I stuff my dictionary to them. Stuff it! I will never give my things to their filthy hands. At least three of my friends can prove that they grabbed it! Well, I hope we will become friends and pay the repair fee.

My School Life In Singapore

My life in school is wonderful. But something dreadful happen. My best electronic dictionary is ruined by two worst students. They grabbed it. Then it DROP down at floor. Its screen cannot be use any more. Their parents promise they will pay the repairing bill.

Some students in my school also smoking in school. I don't know that is there any student in my old school smoking too!
