can any one prove that 0 is neither positve or niethe negative?

Answer 1

if zero is positive when you add it to some number the value of the number should go up.it doesn't.if it is negative when we add it to some number the value of the number should go down.it doesn't.so zero is neither positive nor negative

Answer 2

Basics: what do "positive" and "negative" mean?

From http://www.mathwords.com/p/positive_number.htm :
"Positive Number
A real number greater than zero. "
"Negative Number
A real number less than zero."

So the "proof" follows straight from the definition, it is not a property of the number.

If you wanted to define positive as ">= 0" and negative as "<= 0" you very well could, it would just mean rephrasing some statements for the new definitions. This would make 0 both "positive" and "negative", for these definitions. (how could it be both? Because they are defined that way, just like with the above definitions 0 is both nonnegative and nonpositive)

Answer 3

first
because
positive is > 0
and
negative is < 0

second
assumption = 0 is negative
negatif times negative = positive
but negative times 0 = 0, so 0 is not negative
but 0 * 0 = 0, so 0 is not negative

assumption = 0 is positive
negative time positive = negative
negative times 0 = 0 , 0 is neither negative or positive

Answer 4

Zero (0) is the medium for all numbers.

Zero (0) is the starting point for both.

Zero (0) is nothing where positive and negative #'s are something.

Answer 5

Yes,I can prove that 0 is neither positive nor negative because you draw thw number line it remains in the center it is exactly in the middle neither to the positive side and nor to the negative.

Answer 6

We find the positive and negative numbers on the number line. Zero is at the centre. To its left are negative numbers. To its right are positive numbers. Also it does not obey the rules of multiplication of sighns. For example: +*+=+, +*-=-, -*-=+ The moment you bring zero the sign looses its meaning and anything multioplied by zero becomes zero.

Answer 7

Simple Zero is nuetral. It is not positive or negative.
Good Luck!

Answer 8

negative no. are towards left side of 0&positive no's. are towards right side of 0.Means 0 is the reference pt.i.e. its position is fixed.So 0 is neither +ve nor -ve.

Answer 9

Do you see a sign of Negative? NO!!!!!!!!!! Obvious....... he ruling is a number having no sign of negative is positive so 1,2,3,4.................... are positive but zero is not secluded there because in the groupiung opf rational and irrational , zero has its own group--- ZERo also.
