Most formulas students need to learn are actually quite intuitive when you replace the symbol with a one or two word description. But they'd rather force you to memorize the symbol.
It's like forcing you to read obfuscated code. I find it draining with zero benefit to most learners.
Reducing math to words means English math is different from Chinese math. If I, a native English speaker, were to look at such math, I would have to more or less take it on faith that the translation I'm reading is accurate. And god forbid I'm trying to read a translation of a work done jointly by (say) a Romanian and a Chinese.
The symbols generally remove ambiguity. Consider the English word "bi-weekly." It's so muddied that it is almost useless. It means either twice a week or once every two weeks. It means, literally, both multiplication and division; and context is rarely helpful for this particular word.
You can certainly use the symbols poorly and ambiguously, as many viral "Solve this math problem!" memes exemplify. But used properly they're generally clear, concise, and well-defined.
I do, however, have one nitpick about symbols, and that's with the use of the ellipsis in math. You'll often see things like {1, 2, ..., n} which is generally intended to mean (say) the natural numbers up and including to n. But does it? Couldn't it also represent powers of 2? Or the set of fibonacci numbers? And since it is a set, order doesn't matter. Almost anything at all could be in that set. We can only be sure it's not something like "all the odd numbers" because 2 is in the set. Frustratingly, it's not even necessary in most cases, since we have set-builder notation and other tools.
I'm not saying that math shouldn't be using symbols, I'm saying it's near intentionally hostile to those first picking up the subject. If the goal of math education is to provide the groundwork of understanding to the general populace... Cater to the general populace. The vast majority of those folks are not going to be discussing complex math across several languages.
They're going to be using it for accounting, taxes, construction, cooking, etc. They don't need to memorize an entire language to do that effectively, and we shouldn't be wasting their time in school trying to make them.
Those that choose to specialize are welcome to. In my opinion that doesn't justify the use of specialized language in basic education settings.
You'd use a different notation then. `{1, 2, 4, ..., n^2}` or `{2^0, 2^1, ..., n}` or something similar which indicates what you mean. There's nothing wrong with elipsis, if you spend a second thinking about what you're writing.
If someone wanted to be obnoxious and confusing then they could say: Haha, `n` is not a symbol either; I'm using base-50 and it's digit 23(10). So you can't really stop bad / intentionally misleading communication.
Yes, some foundations of facts are needed. For example, there's some very basic operator precedence that students should internalize. And history inevitably does involve names and dates. But too much attention is probably devoted to remembering whether a battle was fought in 1746 or 1750.
It's somewhat understandable because testing for those things is easy and unambiguous. But it's unfortunate anyway.
I think Latin is still used as part of the traditional service, but it's mostly ritualistic. What I remember from attending Catholic services years ago is a lot of standing up and sitting down while chanting in Latin, followed by a sermon delivered in English.
Can you give some examples of this?
