  National Service Training Program Civic Welfare Training Service

  Authors: Arnold L. Espinas,  Propecasio D. Dalangin,  Miguel R. Santos,  Marilyn T. de Jesus

  This reference text is a result of a long search for the appropriate materials for the Civic Welfare Training Service (CWTS). One of the principal aims of the NSTP is to instill in the minds of the young Filipinos the culture of volunteerism. But developing a high sense of volunteerism is not enough to make the young citizens become effective agents of development. In order to become an effective community worker, each student of CWTS must possess not only the ability to identify the problems of a community. He must also exhibit the ability to understand causes and effects of those problems which will provide great help in formulating the kind of intervention needed to confront them.

  The task of student community workers is not easy, especially on the part of those still in the process of gaining accurate perspective of the dynamics of the community. Each community is characterized by various complexities of sociocultural realities. That is indeed the reason why the authors believe that there can never be one written material capable of providing complete answers to the issues of even one community. But even so, this reference text hopes to share relevant information that will encourage young individuals to become empowered members of the society to which they belong. Empowerment would mean being always ready to initiate actions instead of just being plain participants in any community building efforts.

  Mastering College Algebra Through Drills

  Authors: Leo L. Lactuan,  Imelda R. Lactuan,  Lerna L. Ayco,  Juliana B. Arquero,  Marichu G. Mozo,  Mary Jane A. Bundac,  Siote I. Wy

  Algebra is believed to be the queen of Mathematics. It encompasses all the other fields of Mathematics. One specific subject is College Algebra which is a basic subject in Mathematics for college freshmen under the umbrella of General Education required subjects. The rich experiences of mathematics mentors find many students to be math lovers but a voluminous number are anxious about the topics covered in the said subject or related subjects.

  The ultimate goal of the authors is to pave the way for optimism in facing the challenges of teaching or learning mathematics topics, particularly in College Algebra. Hopefully, the prepared roster of objectives, presentations of concepts/rules/ properties/theorems and examples, required answers to drills (both algorithmic and practical applications), and the chapter tests are alleys to attain the goals/objectives of this book that are made easy and convenient for both the teachers and the students_
  The book is likewise designed to be preparatory to Advanced Algebra as it includes topics that are arranged in hierarchy of necessity/importance. Hence, may the wish be realized_

  The authors would like to express their profound gratitude to the authors of their references, the PSU and WPC administrations, with able leadership of Dr. Deter S. Sespeñe and Dr. Elsa P. Manarpaac, respectively.
  The same amount of gratitude is extended to authors' students, Ma'am Bot Corpuz, Mutya Publishing House, Inc. through Mr. Arnel Tedranes, Ms. Luisa Temblique and Ms. Nerissa Gabelo and mare importantly their families, who serve as their inspirations.

  Above everything the authors are indebted to the Omnipotent God, the source of their strength, knowledge, wisdom and everything.

  Bussiness Mathematics

  Authors: Jocelyn L. Reyes,  Gemma S. Legaspi,  Lourdes P. Gonzales

  Business Mathematics, sometimes called consumer math or commercial math, is mathematics used by commercial enterprises to record and manage business operations. Business mathematics is an important tool in accounting, inventory management, marketing: sales forecasting and financial analysis.

  The emphasis of Business Mathematics in the tertiary curriculum is on computational skills and practical application. It also includes a review of elementary arithmetic including fraction, decimals and percentages. The practical applications typically include checking accounts, price discounts, markups and markdowns, payroll calculations, and simple and compound interest Luckily, even if mathematics is not one of the student's strengths, there are several avenues available for learning business math. The syllabus-based work text in Business Mathematics is one of them.

  Although many of the skills necessary for business success are related to interpersonal savvy and marketplace knowledge, most well-rounded business people need to know basic math skills, ideal for financial reports and other vital business documentation.

  Business mathematics prepares the students in making general business decisions, like whether to expand into a new branch, whether to hire another employee, or if a commodity is marketable. Knowledge of business mathematics makes calculations less tedious and time-consuming, saving the business and its customers time and money.
