I had a thought this morning... (Sorry to all you maths haters out there.)
is -1 a prime number. a prime number has got two factors itself and 1. Therefore -1 has 1 and -1. Therefore is -1 a prime number.
Anyone caught smoking at Layer Road will be buried in the
centre circle by the forking groundsman, with only their head
showing, and left there during the second half.
Previous threats of electrocution, being made to listen to Will
Young and being hung from the floodlights have
failed to discourage all the smokers.
If Cardiff players had to stand and pay respects to an English national anthem, would they? I don't think so.
But Arsenal players manage to do it.

Interesting point, but it's not.
A prime number has to be positive, by definition, hence -1 is not a prime number.
If you think that -1 is a negative prime number, then the answer is also "no", because a negative prime number is defined to have 4 different factors: 1, -1, itself and negative itself.

Hmmmm... You've got a point but i thought you had to have a whole number.

The square of any negative number is a positive number. The negative number needs not be a whole number.
e.g. (-2)^2 = 4 and
(-0.2)^2 = 0.04
The square root of a negative number is imaginary. Remember this, children

.
e.g. (-4)^0.5 = 2i
Edit: forgot to add example.

nope... try and find the root of negative 1... even calculators cant do that cos it goes from infinity to negative infinity...

Hehe, your calculator sucks.
...
I mean...
No, it doesn't go from infinity to negative infinity.
The answer to your question is i.

*Cries, because nobody believes her*.
Ask a FOmar then. I'm sure he'll tell you it's true. Him with so much MST and all, well, third highest. Whatever ... Now I shall stop spamming and leave this thread.
*Ryuker!*
