Is 0 an Integer?

Is 0 an integer? The answer is yes. By definition, integers include positive numbers (1, 2, 3, ...), negative numbers (-1, -2, -3, ...), and zero. Integers are whole numbers without decimal or fractional parts. Since 0 does not have a decimal or fraction, it qualifies as an integer. Furthermore, 0 plays a crucial role in mathematics as the center of the number line, separating positive and negative numbers, and serving as the neutral element in addition.
