Arabic numerals: Theory of “وهدَفي حسابْ”: My goal is to calculate

by Abdelhai Doukali

As the author of the book "Arabic Theory of 'My Goal is to Calculate' (وهدَفي حسابْ)", I present a comprehensive analysis of the origin, significance, and evolution of Arabic numerals. The theory proposed in this book revolves around the motto "وهدَفي حسابْ" (translated as "My goal is to calculate"), which encapsulates the essence of Arabic numerals. In this book, I delve into the historical and cultural context of Arabic numerals, highlighting their Arabic nature. I argue that the forms of Arabic numerals are derived from the letters of the Arabic alphabet, making them inherently Arabic. I emphasize the Maghrebi origin of these numerals, crediting their creation to a Moroccan scholar. The usage of Arabic numerals originated in Morocco and has persisted throughout history. Furthermore, the book explores the relationship between Arabic numerals and the "Ghubariya" method of calculation. This method encompasses various mathematical operations such as addition, multiplication, subtraction, division, and fractions. The discovery of Arabic numerals coincided with the development of this calculation method, further solidifying their significance. The main objective of the book is to dispel misconceptions surrounding Arabic numerals and establish their authenticity as an Arabic invention in 792 CE. By addressing common misconceptions and examining historical evidence, I present a coherent and compelling argument for the Arabic origin of these numerals. In conclusion, "Arabic Theory of 'My Goal is to Calculate'" offers an in-depth exploration of the history, cultural context, and significance of Arabic numerals. This book provides valuable insights into the development of these numerals and their inseparable connection to the Ghubariya method of calculation, ultimately affirming their Arabic identity.
