Arithmetical Wonderland is meant as an unorthodox arithmetic textbook for college kids in simple schooling, in a contents direction provided by way of a arithmetic division. The scope is intentionally limited to hide in basic terms mathematics, even if geometric components are brought at any time when 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 prompted no longer through the topic itself, yet via the language of arithmetic. during this e-book, 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 lads are studying excessive mathematics or easy quantity concept from Alice, and the reader is carried alongside during this educational exploration. therefore 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 particularly unorthodox questions. for example, Alice tells the twins that six divided by means of 3 is 2 merely due to 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 quite early, resembling the thoughts of divisibility and congruence.
