In Bulgaria there is a little yellow book that carries all the rules in mathematics one would need through all of K-12 and then some. It has quadratic formulas, limits, trigonometry (including sin/cos conversion tables), not as many physics formulas though. Everything is explained succinctly as well. It is a commonly used and required book in all schools and it gives you a quick review of anything you need before math competitions, tests, or just brush up after a while. There absolutely needs to be a book like that for US kids and the baseline math levels here will rise up substantially.
- belter 5y agoIs it in Cyrillic or Latin ? Do you know if its available online ?
- aanastasov 5y agoIt's in Cyrillic. The official title is "Четиризначни математически таблици и формули".
- anon_tor_12345 5y agogoogled Четиризначни because didn't recognize it as a russian word (it means four digit) and the first hit is that book https://www.book.store.bg/p35401/chetiriznachni-matematicheski-tablici-i-formuli-dimo-serafimov.html https://www.book.store.bg/p35401/chetiriznachni-matematiches...
- lb1lf 5y agoBulgarian is a distinct language using the Cyrillic alphabet (as is for instance Macedonian, Serbian and Ukrainian)
- anon_tor_12345 5y agowikipedia used to have this https://i.redd.it/5ibk260ssqa61.png https://i.redd.it/5ibk260ssqa61.png e.g. i understood the other two words in the title no problem. >Ukrainian i'm from moldova and i speak russian and understand ukrainian pretty easily. calling them distinct languages is true but it's pedantic - it's a very blurry line how mutually intelligible the two languages are.
- lb1lf 5y ago-Similar story where I come from - Norwegian, Swedish and Danish are sufficiently similar that we can mostly understand each other without much effort, especially (my opinion) in writing - Danish pronunciation is far more challenging to grasp than Swedish, at least to my Norwegian ears.
- Kelamir 5y agoIt's not Russian language. Close, but it's not.
- aanastasov 5y agoThe small yellow book might have already fallen out of fashion. I graduated from a math high school in Bulgaria about 10 years ago, and I vaguely remember the yellow book being referred to as if it was popular during the stone age.
- raninepaths 5y agoIs it available in english? Or any other equivalent book in english?
- akiselev 5y agoIt's not really comparable to the yellow book and its meant as a glossary for an older audience, but I've found Mathematical Notation: A Guide for Engineers and Scientists [1] to be useful, especially for reading CS and ML papers.

- CalChris 5y agoThe Art of Problem Solving series has this. The Basics, Vol. 1, and Beyond, Vol. 2, are a lot like that. They aren't course material. AOPS has that with Prealgebra thru Calculus. These are distillations for contest math with explanations and problems.
