The sequence of numbers "..., -3, -2, -1, 0, 1, 2, 3, ..." represents a set of integers that includes both negative and positive values, as well as zero. This sequence is infinite, extending in both directions. The numbers to the left of zero are negative, while those to the right are positive. In mathematics, these integers are used in various applications, such as counting, measuring, and performing calculations. The number zero serves as a neutral point, separating positive and negative integers. This concept is fundamental in fields like arithmetic, algebra, and number theory.
