The sequence of numbers ..., -3, -2, -1, 0, 1, 2, 3, ... represents the set of integers. This set includes both positive and negative whole numbers, as well as zero. Integers are used in various mathematical operations, such as addition, subtraction, and multiplication. Counting with integers allows us to measure quantities, compare values, and perform calculations. The number zero acts as a neutral point, separating positive numbers from negative ones. This system is fundamental in mathematics and is essential for understanding concepts in arithmetic, algebra, and other branches of mathematics.
