Often referred to colloquially as the "bible of advanced pre-university math," this book has been a staple for students sitting for the GCE A-Levels, STPM (Malaysia), and first-year university courses. In the digital age, the search term has become one of the most frequent queries in math education forums.

Lee’s writing style is unique: it avoids the overly dry, theorem-proof-corollary structure of Western texts (like Rudin or Spivak) and instead adopts a approach. He writes for the student who is scared of proofs. This makes his book particularly sought after in digital formats, as students want it on their phones and tablets for quick reference.
