Graduate Management Admission Test (GMAT) Practice Test

Which of the following represents integer numbers correctly?

1. Fractional numbers only

2. Whole numbers only

3. Only negative numbers

4. Any whole number including negative, zero, and positive numbers

The correct answer is: Any whole number including negative, zero, and positive numbers

The concept of integer numbers encompasses all whole numbers, which include positive numbers, negative numbers, and zero. This definition is fundamental in number theory and is crucial for understanding the nature of integers. Integers can be described as the set of numbers that do not have any fractional or decimal part. Thus, they can be represented in a number line that stretches infinitely in both the negative and positive directions, with zero acting as a central point. This means that any whole number, whether it is a positive count, a negative count, or zero itself, qualifies as an integer. In summary, the correct choice captures the complete definition and scope of integers by acknowledging that they consist of negative numbers, zero, and positive numbers, effectively providing a comprehensive view of what integers are.
