Which of the following is true about integer classification?

• A. Only positive numbers are integers
• B. Only negative numbers are integers
• C. Zero is considered an integer
• D. All numbers are integers

Answer: (C)

Zero is considered an integer, and this classification falls within the definition of integers in mathematics. Integers include all whole numbers that can be positive, negative, or zero. This set encompasses numbers like -3, -2, -1, 0, 1, 2, and 3, extending infinitely in both the positive and negative directions. The inclusion of zero is significant because it serves as a neutral number on the integer number line and plays a crucial role in various mathematical operations, such as addition and subtraction. In contrast, the other options misrepresent the nature of integers, mistakenly suggesting that integers must be strictly positive or negative or asserting that all numbers belong to this category, which is not the case since integers specifically exclude fractions and decimals.
