 just_moi Dec 09, 2002 what are composites? lesternoronha1 Dec 10, 2002 Moi, composites are numbers that are not prime. Eg. 4,6,8,9... just_moi Dec 10, 2002 lol... sorry.... didnt know dat *blushes* ... btw since ur such a math luver (noticed from all ur other teasers) where does 1 fit in? is it a prime number or a composite and why? LimnShicks2 Dec 17, 2002 Once I saw the answer I got stumbed on what are composite numbers. lesternoronha1 Dec 17, 2002 Moi, 1 is neither a prime nor a composite number. It is called a special number. just_moi Dec 19, 2002 lester... why? isnt a prime numebr defined as a number that can only be divided by itself and 1 and doesnt 1 fit into that catergory? if not WHY NOT? (i drove my math teacher crazy with this q... she says she doesnt know) *evil grin* lesternoronha1 Dec 19, 2002 moi, here also you will face disappointment then coz even I was taught at school that 1 is not a prime number. It is a special number coz you get the same number when any number is multiplied by 1 and so on. Hence due to special properties 1 is called as a special number. The reason for this I guess is as given above. Princess_Neopia Dec 28, 2002 Gr8 teaser. Princess_Neopia Dec 28, 2002 I agree. There is no lower positive number than 1, It is a "special number". I was always taught at school about prime numbers and the lowest prime number is always 2. Jenna Jan 18, 2003 Nice teaser! kgirlca Jan 31, 2004 I would never have thought of a teaser like this.
