If you read most of the mathematics articles you will be forgiven to think that there is no contributions made by the Middle Ages mathematicians ever. For some unknown reasons the writers will always mention and not missing Greek mathematicians contributions in this case Euclid, and then conveniently and ignorantly skipped about a thousand years by going straight to the Renaissance mathematicians in this particular case Gauss, who's the main character of the article.

This can be attributed at least in part to the collapse of the Western Roman Empire and the relative chaos that followed it in Central and Western Europe. Instead, Indian and Middle-Eastern mathematicians took over in the intervening millennium or so. Men like Āryabhaṭa, Brahmagupta, Al-Khwarizmi, et al made significant contributions to modern mathematical understanding.
