Class 8 Maths Part 1 Chapter 3, A Story of Numbers, follows Reema’s discovery of 4,000-year-old Mesopotamian symbols to trace how humanity invented counting, bases and place-value number systems culminating in the Hindu number system.

What Class 8 Maths Chapter 3 Covers

3.1 Mechanism of Counting and 3.2 Early Number Systems explore one-to-one correspondence, body-part counting, Ishango and Lebombo tally bones, counting in twos, and Roman numerals.

3.3 The Idea of a Base uses the Egyptian base-10 hieroglyphic system and base-5 landmark numbers to show how grouping by powers of a base works and why non-positional systems need endless new symbols.
