Transcript
Reema's CuriosityThe story begins with a girl named Reema who finds a piece of paper with "strange symbols" on it. She shows it to her father, who explains the symbols are a way of writing numbers from the ancient Mesopotamian civilization, which flourished about 4000 years ago in the region of present-day Iraq. This discovery sparks Reema's curiosity, and she asks the fundamental questions that the chapter goes on to answer: Since when have humans been counting? What was their need for counting? Since when have people been writing numbers in the modern form? How would the Mesopotamians have written 20? 50? 100?
