Are there numbers that are either negative or positive?

Sci, numbers yielded from even roots are either negative or positive, are they somewhat special or something?
>>
0 is neither negative nor positive.

>>7694525
0 is not a number.

Kill yourself

>>7694477
when one says that ±x is the root of y, what one really means is that x is a root of y and -x is also a root of y.
>>
>>7694552
but... ±x can be also understood as a new type of number that can be either positive or negative?
just asking...
>>
>>7694587
No.
>>
>>7694590
Why?
>>
>>7694604
not well defined in the sense of a real number
of course you can define new numbers like this to be equivalence classes of cauchy sequences converging to x and mutliplying (-1)^n, but why would you?

I have made a decision upon reading this post. I will never ever venture onto /sci/ again.

What the fuck mate.
