All three are.
The product of anything and 0 is 0.
no an integer is only 0 1 2 3 and so on
2
a negative integer is -1,-2,-3 and so on, but not -2.5 or 0 a positive integer is 1, 2, 3 and so on but not 7.2 or 0
No, it is not a multiple of 0. Only 0 OS a multiple of every integer.
A number between 0 and 1 is a fraction.
An integer is a number with no decimal places which can be positive or negative. If expressed as a fraction, the integer would have a denominator of 1. Contrast this with natural numbers (1, 2, 3, ...) and whole numbers (0, 1, 2, 3, ...); an integer would be ..., -2, -1, 0, 1, 2, ...
It is: 1 or -1
It might seems like it, but actually no. Proof: sqrt(0) = 0 (0 is an integer, not a irrational number) sqrt(1) = 1 (1 is an integer, not irrational) sqrt(2) = irrational sqrt(3) = irrational sqrt(4) = 2 (integer) As you can see, there are more than 1 square root of a positive integer that yields an integer, not a irrational. While most of the sqrts give irrational numbers as answers, perfect squares will always give you an integer result. Note: 0 is not a positive integer. 0 is neither positive nor negative.
0 (zero)
Sometimes. For example: (-4) - (-3) = -1 (-4) - (-4) = 0 (-4) - (-5) = 1
0.
