Arithmetical Wonderland is meant as an unorthodox arithmetic textbook for college kids in trouble-free schooling, in a contents direction provided by means of a arithmetic division. The scope is intentionally constrained to hide simply mathematics, although geometric parts are brought each 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 brought on no longer by means of 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 taking a look Glass. the men are studying excessive mathematics or user-friendly quantity concept 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 e-book has huge intensity. It examines many arcane corners of the topic, and increases relatively unorthodox questions. for example, Alice tells the twins that six divided by way of 3 is 2 in basic terms due to an implicit assumption that department is meant to be reasonable, while equity doesn't come into addition, subtraction or multiplication. a few issues frequently no longer lined are brought really early, akin to the suggestions of divisibility and congruence.
