# Introduction to Basic Algebra

Algebra is a branch of Mathematics, which was originated by an early Muslim mathematician “Muhammad Bin Musa Al-Khwarizmi”.

He wrote a book on algebra “Al Jabar-wa-Al-Muqabalah”. The word algebra has been taken from the title of this book. “Al Jabar”. In arithmetic we deal with specific numbers $\ldots , - 3, - 2, - 1,0,1,2,3, \ldots$ while in algebra we deal with number as well as letters of the alphabets $a,b,c, \ldots ,x,y,z, \ldots$ where alphabets represent unspecified numbers. The same basic operations of arithmetic $+ , - , \times , \div$ are also used in algebra.
