Publisher's Synopsis
Solving Equations for Unknowns is the Foundation of Daily MathematicsEquations are everywhere in applied mathematics. Whether we work with elementary business mathematics, or in a field of science or economics, or even have to read the news, it is important to know how simple, simultaneous, and quadratic equations work, and to master how to solve them both mentally and with the aid of calculation devices and computers.Elementary algebra is a very useful technique to model the world around us.Equations help us solve problems that we encounter every day - for example, if we want to calculate the current age of someone we went to school with, or if we want to find out how much money we would need to buy a particular combination of sweets. Algebraic equations - whether simple, simultaneous, or quadratic - help us convert the real world into mathematics, and help us give precise answers to these real world questions.This book can either be used as a refresher course for the concepts of equations that might have rusted over time (and help you drill through those concepts with 5600+ exercises) or can be used as a textbook to learn the concepts from scratch.Once you reach the end of the book (there are hundreds of hours of content to go through) you will, indeed, be able to solve any equation that you are likely to encounter in daily life. No longer will variables like x and y be cryptic or scary; you will be able to find their values at a moment's notice.Algebra Is Easy!
