## Abu, Kamil Shuja

Egyptian Muslim mathematician, also known as al-Hasib al-Misri, the Egyptian Calculator (or Reckoner). His full name was Abu Kamil Shujaʿ ibn Aslam ibn Muhammad ibn Shuja. Very few biographical details are known concerning Abu Kamil, but his productive peak appears to have been at the end of the ninth century. The year of his birth and the year of his death are known with a decent degree of certainty as he is known to have died before al-Imrani (who died in 955) but to have lived well beyond al-Khwarizmi (who died in 850). A direct successor in the development of algebra to al-Khwarizmi, his texts on algebraic theory helped to form the groundwork for later mathematicians, including al-Karaji. Fibonacci would later adopt his mathematical techniques.

Abu Kamil worked to perfect many of al Khwarizmi s algebraic methods including work with the multiplication and division of algebraic objects and the addition ...

Either way, beginning in the spring of 1838 Bishop received training from the previous guide and quickly took to the job, learning the several miles of trail and numerous pits, rock formations, and other attractions of his underground place of employment.
