New PDF release: Charming Proofs: A Journey into Elegant Mathematics

Theorems and their proofs lie on the middle of arithmetic. In talking of the only aesthetic characteristics of theorems and proofs, G. H. Hardy wrote that during attractive proofs 'there is a really excessive measure of unexpectedness, mixed with inevitability and economy'. fascinating Proofs provides a suite of outstanding proofs in common arithmetic which are tremendously stylish, packed with ingenuity, and succinct.
