Abū Kāmil Shujāʿ ibn Aslam

Abu Kamil (Arabic: ابو كامل ), full name Abu Kamil Shuja ibn Aslam ibn Muhammad ibn Shuja, was an Arab mathematician. He lived from about 850-930 AD and probably came from Egypt, further biographical details are not known. He was al - Hasib al - Misri, " the Egyptian calculator " called.

Root Terme

He has general relationships between root expressions found stuck among others in the following equations, which were erected by him and confirmed by using the binomial.

Or

Algebra

Abu Kamil wrote several mathematical works. In his Algebra (Al- Kitab al - jabr wa'l - muqabala ) he led the algebra Al- Chwarizmis on. He was known for his handling of root terms. The book has been preserved only in Latin and Hebrew translation, the Arabic original is lost. The algebra was used by Fibonacci and Al - Karagi.

Other works

"The Book of rarities of arithmetic " contains six different tasks that lead to systems of linear equations and require integer or fractional solutions, so-called bird tasks.

In addition, a work on surveying of Abu Kamil is obtained. Though further mathematical works are to know, but did not receive the title.
