Arithmetical Wonderland is meant as an unorthodox arithmetic textbook for college students in simple schooling, in a contents direction provided via a arithmetic division. The scope is intentionally limited to hide simply mathematics, although geometric parts are brought every time warranted. for instance, what the Euclidean set of rules for locating the best universal divisors of 2 numbers has to do with Euclid is showcased. Many scholars locate arithmetic just a little daunting. it's the authors trust that a lot of that's triggered no longer through the topic itself, yet via the language of arithmetic. during this publication, a lot of the dialogue is in dialogues among Alice, of Wonderland reputation, and the twins Tweedledum and Tweedledee who hailed from during the having a look Glass. the men are studying excessive mathematics or undemanding quantity idea from Alice, and the reader is carried alongside during this educational exploration. hence many formal proofs are switched over to soothing daily language. however, the booklet has enormous intensity. It examines many arcane corners of the topic, and increases relatively unorthodox questions. for example, Alice tells the twins that six divided via 3 is 2 simply as a result of an implicit assumption that department is meant to be reasonable, while equity doesn't come into addition, subtraction or multiplication. a few subject matters frequently now not lined are brought fairly early, corresponding to the strategies of divisibility and congruence.
