Introduction to Basic Algebra

Algebra is a branch of mathematics which was originated by an early Muslim mathematician named Muhammad Bin Musa Al-Khwarizmi.

He wrote a book on algebra called “Al Jabar-wa-Al-Muqabalah”. The word algebra is 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 numbers as well as letters of the alphabet 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.
