0 Guest Posted March 23, 2008 Report Share Posted March 23, 2008 (edited) 0 is neither prime nor composite. Nor positive nor negative. Edited March 23, 2008 by Noct Quote Link to comment Share on other sites More sharing options...
0 Guest Posted March 23, 2008 Report Share Posted March 23, 2008 (edited) if it is not + or - then it is both at the same time then it is positive and negitve at the same time and if it is neither prime nor composite the it is one or the other so then it is both at the same time. If they are opposites then what i said is the same thing you said. Edited March 23, 2008 by Jordanmax Quote Link to comment Share on other sites More sharing options...

0 Guest Posted March 23, 2008 Report Share Posted March 23, 2008 Well not knowing what a composite number is, I looked up on Wikipedia, and it seems that prime and composite are mutually exclusive qualities of a number (composite has a divisor other than one and itself; prime has one and itself only) - it's either one or the other. The FIRST composite number listed is 4. How do you say 0 is a composite number? Quote Link to comment Share on other sites More sharing options...

0 Guest Posted March 23, 2008 Report Share Posted March 23, 2008 First wikipedia is not always right and you make and it is not prime because zero /zero is undifined and so is zero/ anything else. Quote Link to comment Share on other sites More sharing options...
0 bonanova Posted March 23, 2008 Report Share Posted March 23, 2008 What is the only number the is prime and composite. Since by definition a composite number is not a prime, and in particular neither 0 nor 1 are primes nor composites, I am interested to hear what the OP thinks the answer is.

A prime must be a natural number. So the first prime number is 2, not 0. Quote Link to comment Share on other sites More sharing options...

0 Guest Posted March 23, 2008 Report Share Posted March 23, 2008 (edited) technicaly yes zero is not a natural number but negative numbers are not all prime Edited March 23, 2008 by Jordanmax Quote Link to comment Share on other sites More sharing options...
0 Guest Posted March 23, 2008 Report Share Posted March 23, 2008 bonanova's rant on zero states that zero is a natural number I might be missing it, but I don't see where he says it is. Quote Link to comment Share on other sites More sharing options...
0 Guest Posted March 23, 2008 Report Share Posted March 23, 2008 Ok captain, if the Wikipedia definition of a composite number is wrong, then go on record and say how my recapitulation is wrong, and tell me what a composite number is. Instead of shouting at the rain maybe provide some justification here. Quote Link to comment Share on other sites More sharing options...

I never said your definition was wrong im just saying that you can change wikipedia i could change it right now to say a composite number is bananas.

0 Guest Posted March 23, 2008 Report Share Posted March 23, 2008 I just want some justification on the answer of zero and "official" definitions (official being from the math authority here, Jordanmax ) of prime and composite. Quote Link to comment Share on other sites More sharing options...
0 Guest Posted March 23, 2008 Report Share Posted March 23, 2008 Oh, and 0/0 is undefined, correct. You also said "0/anything else" is undefined. 0/2 = 0, 0/anything = 0. Quote Link to comment Share on other sites More sharing options...
0 Guest Posted March 23, 2008 Report Share Posted March 23, 2008 I just want some justification on the answer of zero and "official" definitions (official being from the math authority here, Jordanmax ) of prime and composite. A quick layman's definition of a prime, is a number that can only be divided by itself and 1 evenly (Without a remainder). 7 is a prime number because no other number divides evenly. 8 is divisible by 2 and 4, so it is not prime. A composite number is a number that can be divided evenly up into prime numbers smaller than itself. so 8 is composite because 2 and 2 and 2 are prime, so they make up 8. One explanation: 0 can be divided by any number with no remainder, so it's not prime. no prime numbers multiplied together can equal 0, so it is not composite.

If you have 0 peices of pizza and you divided by 2 how many do you have. WELL you cant divid 0 Quote Link to comment Share on other sites More sharing options...
0 Guest Posted March 23, 2008 Report Share Posted March 23, 2008 If you have 0 peices of pizza and you divided by 2 how many do you have. WELL you cant divid 0 That's not dividing by 0... That's dividing by 2 Quote Link to comment Share on other sites More sharing options...
0 Guest Posted March 23, 2008 Report Share Posted March 23, 2008 That's not dividing by 0... That's dividing by 2 I know you are dividing zero not dividing by zero Quote Link to comment Share on other sites More sharing options...
0 Guest Posted March 23, 2008 Report Share Posted March 23, 2008 I know you are dividing zero not dividing by zero Oh sorry, I see what you were saying my mistake completely! But yes you can divide 0 by anything you want (except 0). If i have 0 pieces of pizza and 2 people, how many pieces does each person get? 0! you can divide 0 by anything you want (except 0), but the answer will always be 0.
