Negative numbers can be integers. Only irrational can't be integers. If it can be written as a ratio then it's an integer.
An integer is any whole number. Negative whole numbers are called Negative Integers. Any decimals or fractions that are not whole (1/2; 3.14) are not integers. Fractions that ARE whole (2/2) are integers. And yes, 0 is an integer.
