Simplified Mathematics (Revised Version)

Book excerpt: This book Simplified Mathematics (Revised Version) is a revised version of the book simplified mathematics. Some new topics have been added to complement the original book. These topics will add to students knowledge obtained from the first book. This book will serve as a useful tool for students who are preparing for entrance examinations into colleges and universities. Students in the higher institutions taking courses in mathematics will also find this maths book useful, especially when there is need for improved mathematical foundation for such students.The step by step explanations presented in the worked examples are easy to study since care was taken to sufficiently explain salient points and mathematical ideas. Efforts have been made to achieve a complete and simplified explanation of every example given in this textbook. Many worked examples have been included in each topic in order to fully cover every complexity the topic might contain.Numerous exercises at the end of each chapter are intended to test students' understanding of the topic. Therefore students are thus presented with an effective means of self-assessment whereby they can determine their individual strengths and revision needs.The topics covered in this book include: Linear equation and equations with fractions Number basesStandard forms and approximationsLaws of indices Laws and theories of logarithmsModular arithmetic Change of subject of formulaeVariationPercentage errorSequence (Including Arithmetic and Geometric Progressions)Series (Linear and Exponential Series) Surds Square root of surdsThese topics have covered some areas under linear algebra and numbers and numerations.Readers with mathematical mindsets will find these topics well simplified, thereby making mathematics more interesting. A constructive overview of this mathematics textbook will be highly appreciated from buyers so as to give an overview to others who intend to purchase a copy of this text, and also to be a form of advice for the author to use when revising the book.
