The sheer audacity to say this. This is shameless approbation and THEFT!

Forget about Algebra, Early Muslims did not not know of any number greater than 400. They did not even know about the concept of "thousand" until 8th century. They thought 14+13=24.

Indians knew Algebra much BEFORE Islamic prophet & religion was even born. Attached is Bakhshali Manuscript dating back to 3rd century CE. It is an Algebraic treatise. Have you anything like this from the Arabian desert? No, you simply plagiarized Algebra from Indians!

The first Muslim who wrote a treatise on Algebra was Al Khwarizmi. The English word 'Algebra' comes from his work. But he was not from deserts of Arabia. He lived in a region which had Hindu past. He studied Hindu sciences and mathematics. It is an academic consensus that Al Khwarizmi's work is taken from Hindu mathematics.

The Bakhshali manuscript, carbon dated to 3rd century CE, is an ancient Hindu treatise on Arithmetic and Algebra.

It deals with simultaneous equations, quadratic equations, arithmetic geometric progressions & quadratic indeterminate equations.

Bakhshali isn't earliest Indian Algebraic treatise. Early Algebra is found in Shulba Sutras dating back to at least 800 BC. Traditional Algebra reached its pinnacle in the works of Aryabhata & Bhaskara. What makes Bakhshali special is it offers mathematical proof to its theories

The earliest work of "Arabic Algebra" is the "Al-Kitāb Al-Jabr wal-muqābala" by Al Khwarizmi. The term "Algebra" comes from this book ("Al Jabr"). Before writing his treatise, Al Khwarizmi visited India. His book is a plagiarism from Indian Mathematics and an obvious one at that.

For example, compare the derivation of PI given in his book Algebra to that given by Aryabhata 300 years before his time.

Left: Aryabhata Right: Khwarizmi

Not just the value but even the terminology used is identical.

The fact that Khawarizmi heavily plagiarised from Indian Mathematicians has been known to western scholars since 200 years. Henry Thomas Colebrooke was a historian and Mathematician. Writing in 1817, Colebrook came to the conclusion that Khwarizmi owed his Algebra to Hindus.

After carefully examining the works of Khawarizmi and ancient Hindu mathematical texts, Colebrooke says:

"The inevitable conclusion is that Khawarizmi, being conversant with the sciences of Hindus, must have learnt Algebra from Hindus"

Another European Mathematician Pietro Cossali also came to the same conclusion after diligent research.

He says: "Khwarizmi was skilled in Indian tongue and fond of Indian matters. He translated Indian works. He was first instructor of Muslims in Algebra. Not having taken Algebra from Greeks, Khwarizmi must have either invented it himself or taken it from Indians. The latter (taking Algebra from Indians) seems more probable"

In a more recent work, Starr Fredrick provides further insights.

1) Khawarizmi had deep interest in Indian science and math.

2) Indian culture exerted a powerful influence in Khwarizm.

3) Hinduism exerted influence on Khwarizmian calendar.

The Arabs were invading nomadic armies from Arabian deserts. They lacked most basic education and literacy.

Even after conquests, Arabs were living in tents.

What made them them take any interest in Indian Mathematics? What made Khwarizmi write his work? Who civilized illiterate desert nomads? This is a question I will answer in my thread.

Until 770, which is almost 140 years AFTER the prophet, there was not a SINGLE Arabic work on science. Not one Arabic work on Math. Not one Arabic work on Medicine. Absolutely nothing.

There is no exception to this rule. Until 770, Arabs produced ONLY religious works or simple poetry. There is no exception to this rule.

What had changed in 770? This is a question I will answer in this thread.

Even after Islamic conquests, most 7th century Arabs lived in tents.

Even the emperor of Arabs, their Caliph Muawiya, lived a very small shack constructed of only brick and timber.
He did not have a proper roof and there were birds all over his 'ceiling'.

This person was not just a desert chief but an emperor who conquered everything from Constantinople until Afghanistan.

Needless to say, there was no knowledge of Algebra among these people.
