Ideal for a first course in number theory, this lively, engaging text requires only a familiarity with elementary algebra and the properties of real numbers. Author Underwood Dudley, who has written a series of popular mathematics books, maintains that the best way to learn mathematics is by solving problems. In keeping with this philosophy, the text includes nearly 1,000 exercises and problems--some computational and some classical, many original, and some with complete solutions.The opening chapters offer sound explanations of the basics of elementary number theory and develop the fundamental properties of integers and congruences. Subsequent chapters present proofs of Fermat's and Wilson's theorems, introduce number theoretic functions, and explore the quadratic reciprocity theorem. Three independent sections follow, with examinations of the representation of numbers, diophantine equations, and primes. The text concludes with 260 additional problems, three helpful appendixes, and answers to selected exercises and problems.

Lovely dress. Good quality but squashes my boobs
Size: Small, Color: Navy Polka Dot
Size chart is accurate but if you have a large bust consider sizing up, the bust area doesn’t have much room so expect lots of cleavage if you have a large chest. It kind of squashed my boobs and doesn’t provide the best support. This is best for smaller chests.
The quality is nice and it washes well. This can be worn with flats on a casual day or dresses up with some heels. This dress is lined and not see through.
