ok want to do something novel

fucking tease you open talking about the real #'s and then spend the rest of the page talking about rational numbers, which I hate (for aesthetic reasons)
ok walking through the proof that r^2=2 does not have a solution in the rational #'s
makes sense ok moving on

god this textbook is full of itself lmao
"Set theoretically the rational numbers can be defines as sets of ordered pairs..."
I do not know what "ordered" means
DON'T TELL ME

oookay I GET it but I do not like the language it feels very slippery and hard to translate into a verbal explanation of my own
yada yada set operations I have seen this many times
gonna close the book and see how far I can get remembering this tho

sets from memory
I will not elaborate

god this book is a tease it isn't getting to the thing it said was critical until the end of ch. 1
devious

I will just have to make mistakes until it makes sense
wtf is the projection function
why did the book stop giving me pictures 
legit angry nobody taught me basic things about sets in middle school
