What do we call an integer that cannot be divided evenly by 2?

An integer that cannot be divided evenly by 2 is defined as an odd number. Odd numbers are whole numbers that, when divided by 2, always produce a remainder of 1. This means they do not fit into the category of being even, which are integers that can be divided evenly by 2, resulting in no remainder. To further clarify, whole numbers encompass all non-negative integers, including both even and odd numbers, while integers include both positive and negative whole numbers. Therefore, the term that specifically identifies numbers that are not divisible by 2 is "odd number." This makes the identification of odd numbers as those that leave a remainder when divided by 2 clear and consistent with standard mathematical definitions.
