Real Number System

The Real Number System is a way to categorize all the numbers we commonly use. It includes integers (like -3, 0, and 5), fractions (like 1/2 or 3/4), and irrational numbers (like π and √2) that can't be expressed as fractions. Real numbers can be positive, negative, or zero, and they can be placed on a number line. This system is fundamental in mathematics, enabling us to perform calculations, measure quantities, and describe real-world phenomena accurately. Essentially, it encompasses all the values that can represent a distance or magnitude.
