Could you clarify exactly what you mean by this? I'm going to speak much more broadly than in the previous post, but other non-European societies made considerable contributions to the development of mathematics. Ancient Chinese mathematicians developed early methods for solving linear congruences and "Master Sun's" contains an early demonstration of the "Chinese Remainder Theorem". Ancient Indian mathematicians made contributions particularly to trigonometry and trigonometric functions while Middle Eastern mathematicians greatly improved the development of algebra as we know it today (Al-Khwrazmi and Omar Khayyam particularly note-worthy in their contributions) and perhaps most notably shaped our system of numerics and representation of numbers (a subtle but important point is also how they developed the concept of a number).In my mathematics class I had a teacher that said a similar thing to what you said and he was accused of being "Eurocentric"
how would you respond to that
Few would play-down the accomplishments and contributions of many other non-European civilisations to mathematics, but it would be simply false to ignore how mathematics as we know it was developed very significantly and substantially by predominantly European societies (especially if you're including the Ancient Greeks as a European civilisation; Euclid himself , and Diophantus, was/were anachronistically an African mathematician), particularly (during Ancient Greece presuming your including them and) from the fourteenth century until the nineteenth century (which charted things such as the shift from synoptic algebra to symbolic algebra, the solving of general forms of cubics and quartics, the fundamental theorem of algebra, the early development of calculus, the development of complex numbers, the development of abstract algebra and the beginning of the study of modular forms and elliptic curves both of which are incredibly important modern concepts via Gauss's Disquisitiones Arithmeticae, and that's not to mention the development and formalisation of analysis). Mathematical achievements and contributions now are certainly less derived from European sources, but it is not at all simply imparting a European bias to acknowledge that Ancient Greece mathematicians were considerably more advanced and important to the development of mathematics as we know it today than the Ancient Egyptians were, and it's not really false to acknowledge that in a broader sense European societies did substantially develop mathematics as we know it even though other regions made their own large contributions (particularly India and what we would now refer to as the Middle East).
It bares emphasis that it is loosely speaking. Primarily, this is because The Ancient Greeks did not think of a 'number' as we do today. I have found lecture notes online from a US university (specifically dealing with Eudoxus and the theory of proportions, and how it compares to how real numbers were formalised) here: https://www.math.uh.edu/~shanyuji/History/h-8.pdf if you wish to read a bit more. It's written in a rather accessible manner and seems to not require much mathematical background, but I will be honest that I've only really skimmed it, if you want to read some more about that in a little more detail. EDIT: Upon reading, it does make some claims, such as claiming the theory of proportions delayed the development of numbers (or a non-geometric approach to mathematics) for two thousand years, that I wouldn't look upon very favourably or as entirely accurate even if I can certainly see why one could make that claim, but it definitely gives a good idea at the very least.
EDIT: Missed some words initially
