Numerals are symbols used to represent numbers. They help us count, measure, and perform calculations. The most common numerals are the Arabic numerals (0, 1, 2, 3, etc.), which are used in many parts of the world. There are also Roman numerals (I, II, III, etc.), which were used in ancient Rome and are still seen today in clocks and book chapters. Numerals can be classified into different types. Natural numbers are the counting numbers starting from 1, while whole numbers include 0. Integers consist of whole numbers and their negative counterparts. Understanding numerals is essential for everyday tasks like shopping, cooking, and budgeting.
