The House of Wisdom, Baghdad

Abu Ja'far Muhammad ibn Musa al-Khwarizmi lived in Baghdad from around 780 to 850 CE. He wrote an influential book in 825 called "Hisab Al-jabr w’al-muqabala" from which the term "algebra" is derived. In this book and his work, al-Khwarizmi helped establish the widespread use of the Hindu-Arabic numeral system and the concept of using 0 as a placeholder in place value notation. He was an influential scholar at the House of Wisdom in Baghdad.

Abu Ja'far Muhammad ibn Musa al-Khwarizmi lived in Baghdad, around 780 to 850 CE (or AD).

He was one of the first to write about algebra (using words, not letters).

Around 825 he wrote the book "Hisab Al-jabr w’al-muqabala", from which we get the
word algebra (meaning 'restoration of broken parts'). This book included many word problems,
especially dealing with inheritance.

Al-Khwarizmi helped establish widespread use of Hindu-Arabic numbers:

1, 2, 3, ...

which replaced Roman numerals (common throughout Europe and the Middle East as a result of
the spread of the Roman Empire), until then:

I, II, III, IV,...

The Hindu-Arabic system was much easier to use when performing mathematical operations,
since it is a base-10 system. Ever tried to multiply using Roman numerals...?

This Islamic mathematician was also instrumental in encouraging the use of the number 0 as a
place holder. For example, the "0" in the number 105 indicates there are no multiples of 10 in
this number - the 0 is just separating the "1" (for undreds) and the "5" (for 1's).

The House of Wisdom, Baghdad

Al-Khwarizmi was a scholar at the House of Wisdom in Baghdad. This group was interested in re-
engaging with the brilliant work of the ancient Greeks, which had been lost and almost forgotten
about, for centuries. Apart from translating the classic Greek texts, they published their own
research on algebra, geometry and astronomy.

The scholars weren't simply producing academic works. They were trying to solve the problems
of the day involving lawsuits, trade, measurement and inheritance.

Al-Khwarizmi's Algebra

The algebra presented in the book "Hisab Al-jabr w’al-muqabala" used words for variables, so it
was not as convenient as the algebra we use today.

"Al-jabr" means "completion" and "al-muqabala" means "balancing". His aim was to solve linear
or quadratic equations by removing negatives using a process of balancing both sides of an
equation. This is the same as what we do in algebra today.

From al-Khwarizmi's name came the word "algorithm".

Muhammad al-Khwarizmi, the "father of

algebra"

•Muhammad ibn Musa al-Khwarizmi was


a 9th-century Muslim mathematician and
astronomer.
•He is known as the "father of algebra",
a word derived from the title of his book,
Kitab al-Jabr.
•His pioneering work offered practical
answers for land distribution, rules on
inheritance and distributing salaries.
•He also developed the concept of the
algorithm in mathematics, which is why
some have called him the "grandfather
of computer science".
•Khwarizmi was one of the most famous
scholars of Bayt al-Hikma (The House of
Wisdom), Baghdad’s intellectual
powerhouse.
•The House of Wisdom was a centre for
the study of sciences, including
mathematics, astronomy, medicine,
chemistry, geography and astrology.
