jesus fucking christ not more math i thought i ended this in high school

people like this are exactly why education will continue to get dumbed down

It's way too long and tedious, school days were long enough that literally every student gets bored of just sitting there, even the ones that have intellectual curiosity. Beginning your life by being bored about learning is detrimental to your future.

The ratios between completely useless trivial crap like plant species memorization, slightly useful crap like grammar rules, and important content like empirical sciences and math (which itself should be more about the reasoning and less about the memorization) are way off too. 20000 hours of compulsory schooling should have a near-100% success rate at breeding non-dumbasses.

This is a joke, right?

Is this math for retards?

>>80269878
Looks like an introduction to fields, typically done in the second semester of an abstract algebra course.

it looks trivial because it is. field axioms aren't interesting, field theory is.

I got a similar book, but it's a bit more complicated than this.
I mean the stuff in OPs pic is common sense, nothing that needs to be written in a book.

>>80269878
You're obviously a retard who has never opened a real math book in your whole life. Like most scum in /pol/ anyways.

>I mean the stuff in OPs pic is common sense, nothing that needs to be written in a book.
so you don't actually know what you're talking about, alright.

>>80267416
Ok now for real OP. Are you being serious? Or is it bait?

By writing it in the book, you're making it common knowledge. Now everyone knows that everyone else also knows it, which is convenient even if everyone already knew it.

What? It has nothing to do with outreach of math

Jesus Christ guys, if you've never studied math since High School it's ok, but please just don't pull shit out of your fucking ass. We do that when it comes to politics because literally you can keep pulling shit out of your ass forever, but not in math.

It's not "making thing common knowledge". It's defining what a Field is, defining the mathematical properties of such a field. The fact that this corresponds with the properties of sum is absolutely irrelevant, nobody gives a shit if it's "easy" or "hard", it's the very beginning of any Linear Algebra book after defining what a group is.

Math is not based on "the common sense". It's not based on whatever you know from before or not. You start with some axioms and the build with definitions and theorems from there.

Jesus fuck /pol/.

*mathematical properties of such an object*, sorry.

>abstract and linear algebra
Looks like set babble to define addition and subtraction proporties to me

>>80267416
It just seems like a lot of abstraction, I learned these properties in the first grade but this format is probably the basis for something more complex thus it is taught in the course right before the complex stuff.

>>80273957
To be honest, it reminds me of a normal Harvard introductory Maths course book.
