Thank you for sharing. Is there a gitbook link?

Also I’m not sure if this is well known but Gemini has a nice quiz/test mode that you can use for learning. Ask it to quiz you on a subject and you can increase/decrease difficulty and keep going. I pair it up with textbooks as a learning tool; not in school or anything just for my own enjoyment.

It would be nice if the unfinished sections had at least an outline so others could fill in the gaps. SIMD for example… :D

Another suggestion - Do append authoritative resources for further deep dive into sub topics/concepts. I'm sure a sliver of the reading audience would love that feature, myself included. Thank you for your generosity & hope to see this repo get enough traction & contributors to fill all the sections.

It's just a regional thing. Neither is correct or wrong. You may as well yell at a french person that the word is "cheese", not "formage".

From the very article you linked:

> In English, the noun mathematics takes a singular verb. It is often shortened to maths or, in North America, math.

For speakers of the King's English, we wouldn't say "econ 101" either. We would say economics.

101 is an interesting number! Winston was taken there in 1984 by a fascist group whose tactics included the rigorous standardisation and abolition of all variation and redundancy in the English language. Nice.
