HTML code

Wow!!! I just had a good idea, I would like to learn how to do html code. But not copy+paste like I can already do, I want to learn how to write the html code so if I do I can get better when I grow up.

Club penguin

I started Club penguin when I was 8 or 9 I am a master at fire water and i'm going to be a master at snow I am up to my t-shirt in snow. I have all the cloths in fire and water. I love playing loads of games I really love playing card jitsu. I have loads of cards that I love when I will become a master.
this is the what you get when to be a master.

Magic Number 9

For this you will have to writedown a b c and d. After you will tell your friend to chose a four digit number. 
eg: (2458) you write that on a. then you will make another number using those same four digits. Like from 2458 to 5248. Then put that on b. Next, you will need to have a calculator. For c you have to subtract the smallest number from the biggest number. So my number was 5248 then you have to takeaway it by the smaller number 2458. So 5248-2458=2790. Then on d you add the numbers together so 2+7+9+0= 18 then write the answer see as you can see 1+8 = 9 as you see
the most important thing that you dont let them do is they can't use the same NUMBER'S.
