Number theory, an ongoing rich area of mathematical exploration, is noted for its theoretical depth, with connections and applications to other fields from representation theory, to physics, cryptography, and more. While the forefront of number theory is replete with sophisticated and famous open problems, at its foundation are basic, elementary ideas that can stimulate and challenge beginning students. This lively introductory text focuses on a problem-solving approach to the subject.

It is impossible to imagine modern mathematics without complex numbers. "Complex Numbers from A to ...Z" introduces the reader to this fascinating subject which, from the time of L. Euler, has become one of the most utilized ideas in mathematics.

The exposition concentrates on key concepts and then elementary results concerning these numbers. The reader learns how complex numbers can be used to solve algebraic equations and to understand the geometric interpretation of complex numbers and the operations involving them.

These simple math secrets and tricks will forever change how you look at the world of numbers.
Secrets of Mental Math will have you thinking like a math genius in no time. Get ready to amaze your friends—and yourself—with incredible calculations you never thought you could master. This book will teach you to do math in your head faster than you ever thought possible, dramatically improve your memory for numbers, and make mathematics fun.

Hidoku is not Sudoku. It's a brand new puzzle game, played on a square or rectangle of any size. Your goal is to fill in the missing numbers from 1 to the maximum number (which is circled) by following one simple rule: consecutive numbers must touch each other either horizontally or vertically or diagonally. In this book there are 150 of these puzzles, which are all solvable by logic and no guessing is ever required.
