Any non-zero integer raised to the power of zero is equal to 1.
Integer n.
The sum of zero and any integer is never zero.And it's still 'integer', not 'interger'.
In mathematics, a multiple of an integer is the product of that integer with another integer. In other words, a is a multiple of b if a = nb, where nis an integer. If b is not zero, this is equivalent to saying that a / b is an integer.0 is a multiple of every integer ().Source: http://en.wikipedia.org/wiki/Multiple_(mathematics)

positive times negative equals negative
There are just three possible cases: Positive integer: positive x positive = positive. Negative integer: negative x negative = positive. Zero: zero x zero = zero.

Chose any non-zero integer k. Then 1/1 = k/k.Chose any non-zero integer k. Then 1/1 = k/k.Chose any non-zero integer k. Then 1/1 = k/k.Chose any non-zero integer k. Then 1/1 = k/k.
By definition, a negative integer is any integer less than zero. Similarly, a positive integer is any integer greater than zero. It should be immediately obvious that an integer cannot be both less than and greater than zero. Therefore, a negative integer cannot be greater than a positive integer.
Zero
Zero.
Any integer above starting at and including zero is a natural number. Anything below zero is not.
Any integer divided by a non-zero integer is rational.
