Query: Instruction by Question

R. P. Burn is an amazing writer for mathematical textbooks.This book follows Burn's typical format; therefore, this text is little more than a collection of (very) brief introductions to terminology and concepts, followed by a long list of questions for each chapter. Finally, each chapter has an answer section.The questions asked typically very short, and at first are very simple and intuitively obvious. As each chapter progresses, however, the questions begin to build from prior questions already answered and express more and more complex concepts.Typically, by the time a chapter has been completed, the reader will have completed one or more complicated proofs typically found in other texts on the same subject-- small bite by small bite at a time.Highly recommended
