This may not be so absurd in the encyclopedic subjects but in mathematics it doesn't make any sense since things follow from each other and, in principle, whoever knows the bases knows everything. All of the results of a mathematical theorem are in the axioms of mathematics in embryonic form, aren't they?” Alfred Renyi ## About This Quote This interpretation was drafted with AI assistance. It is one reading of the quote, not the author's own explanation. Exam difficulty can be gauged by the information bits a student must master; in mathematics, knowledge is cumulative, so bases determine mastery. **In simple terms:** Exam difficulty equals needed knowledge bits. Key Takeaway Master fundamentals to reduce difficulty.
