Not really. Most of us today use the same mathematics but it was not always the case. It turns out mathematics is very much like language. Today we all mostly use the same basic math with a few variations. One thing I remember from my teaching days is that when you go to a new area the first thing you need to know before starting teaching maths is to find out how they do subtraction there. There are at least 5 different ways of doing the simple subtraction eg 27 - 18. We have the Ancient Egyptian mathematics as we have the example workings of their students in mathematics even if we don't necessarily have their teaching text books. They have even been translated, but only the first bit of the translation has been done in most cases so what we had is almost like a Google Translate of their maths. I have just started reading "Count like an Egyptian" by David Reimer. One hypothesis he demonstrates as possibly valid in the introduction, is that addition in not needed in a practical mathematical system counting will do instead. I really must get back into the book.
