It’s a pity that algebra often has such a ‘bad press’ in primary school mathematics for it gives pupils an early introduction to how mathematicians express relationships and use numbers and symbols like a shorthand version of words.

The history of algebra

Ancient mathematician
  • The word algebra has deep historical roots. It comes from the word al-jabr that is contained in the title of the most famous book written by Muhammed Al-Khwarizmi, an Arab scholar who lived in the country we now call Iraq around 800 AD.
  • The book, called Hisab al-jabr w’al muqabala (Calculation by Restoration and Reduction), contains rules to find solutions to equations but was also intended to be a highly practical document that would illustrate how algebra can be used to solve real life practical problems.
