Sometimes Zero can be given a + or a - sign, depending on the system, ie, when two zeros are necessary in computing or floating point calculations (a number may round to zero, but you need to know whether it was rounded up or down).
However, in general, it is not true to say zero is either a positive or a negative number, because it is the exact boundary where one becomes the other.

Which number is a counterexample for the following conjectureConjecture: All integers are either positive or negative.?
A+ 0
If you add a positive and a negative number how can you tell whether the answer will be positive negative or equal?
If the negative number is bigger then the answer will be negative If the bigger number is positive then the answer will be positive. All you do is subtract the two numbers and take the sign of the bigger number Ex (+2)+(-7)=(-5)
Are integers always positive or negative?
an integer is a negative number and a positive number. It is all the numbers, just like a natural number is all the numbers from 1 and up
Is negative 5 greater than positive 0?
Zero isn't positive or negative. All negative numbers are less than zero.There is no such thing as "positive" (or "negative") zero.Also, a negative number is always less than any positive number.
How can you decide if the sum of two numbers is positive negative or zero without actually calculating the sum?
The sum of two positive numbers is always positive, and the sum of two negatives is always negative. If you have a positive and a negative number, there sum can be either, so look at the absolute values to decide. For example -3+2=-1. Since all you care about is the sign, look at the absolute value. If the negative number has a greater absolute value, the sum is negative and if the positive number's absolute value, which is the number itself, is bigger, the sum is positive. If the absolute values are equal, the sum is 0.
