30In one of the books it was given for non negative reals as [0,∞).
Is zero (0) a positive no., negative or both?
Why is the set of non-negative reals defined as [0,∞) and negative reals as (-∞, 0)?

62oh for a moment I thought you were the asish from the last year and just stopped from answering cos i thought it was his question for freshers :) (same name.. try go get the same rank :)
waise 0 is neither -ve nor +ve.. it is zero :)
30:)
But then why the discrimination in the definition of negative reals?
62where is the discrimination?
+ve (0, infinity)
-ve (-infinity, 0)

106look u are urself giving the answer
negative : (-∞,0)
non-negative : R - (-∞, 0) ≡ [0, ∞)
positive : (0, ∞)
non - positive : R - (0, ∞) ≡ (-∞, 0]
30Amazing explanation! Thanks! :)
"non-negative"! the bone of contention! :D
6well 0 is 0
my doubt where do u need these things??i mean there isnt any application of such things...so why are you pondering over it?
