When we talk about integers, we refer to the set of whole numbers that can be positive, negative, or zero. This means that integers include values like -3, -2, -1, 0, 1, 2, and 3, among others.
However, the term ‘whole numbers’ specifically denotes the set of non-negative integers. Whole numbers are the integers starting from zero and include positive values: 0, 1, 2, 3, and so on.
Therefore, in the context of your question, the integers that are not whole numbers are the negative integers: -1, -2, -3, etc. These numbers do not belong to the whole numbers set as they are less than zero.
In summary, integers like -1, -2, -3, -10, and so forth are integers that are not whole numbers because they fall below zero on the number line.
