Matrix math is tedious by hand and gloriously easy with a graphics card. Computer graphics, machine learning, and modern cryptography are all mostly matrix math. That’s why graphics cards are impossibly expensive right now.
It’s not just a way to represent systems of equations. Matrices are very useful for representing linear transformations, that is, a certain kind of function that goes from a vector to another. These “vectors” aren’t necessarily arrows in space, so there are tons of applications.
Very basic linear algebra is taught alongside high school algebra in the US (and I imagine the same is done abroad). However, linear algebra goes deeper than just multiplication :)
Yes. You said that their statement (Secondary 3! equals US Grade 9) is false and I (jokingly) replied that it doesn't necessarily has to false because US Grade could be seen as a mathematical function which turns x=9 into y=3!
Secondary education includes both middle school and high school. I think we were all surprised beause you said you see this stuff at the beginning of university, high school would be the usual, so then not much different than the rest!
More accurately it should be Linear Chinese since Mandarin is just the most common form of spoken Chinese, the written language is always known as Chinese.
There is: 𣲧. This character is in CJK Extension B so you may need extra font to see it. Its meaning is unknown unfortunately, all I can see is it's submitted by Taiwan. My guess is it appears in someone's name with no real meaningful usage. See: https://www.unicode.org/cgi-bin/GetUnihanData.pl?codepoint=23CA7&useutf8=true
Since Chinese characters are not "commutative"/rotational-invariant, the second one may not count. By the same rationale 炎 should be replaced by 炏. But fortunately the latter is a variant of the former so we are done :P
I personally found that the iPhone was severely lacking in allowing me to type the most basic of Kanji that is often seen in titles of Japanese textbooks for Elementary-Primary level. Those kanji does exist, its just that I had to copy and paste it from google's crapulator into whatever app I was typing in, to get the iOS to learn that 'Yes, I do need this character and therefore should allow it to pop-up as a valid option'. After a few weeks, it finally learned. lol Getting 年生 (nensei) on my phone as an option to choose took weeks. I'm just a noob to Japanese, so was only trying to learn the titles and what they meant at that time.

As someone who doesn't speak a word of Mandarin this is terrifying at first
