This textbook presents a selection of technical tools in basic math that foster fluency in working with numbers, measured values and algebraic equations. To this end, the textbook promotes the use of technical tools that are efficient and meaningful. Following the main theme of the textbook, we show how the increasing level of complexity of the problems that we, as humans, solve, leads to the need for the many tools and algorithms that are discussed in the textbook.The textbook caters to the needs of a wide variety of readers. Whether you are someone interested in self-study, a high school, college or university student, a parent, an educator, a scientist, a mathematician, or a linguist, this textbook has something for you and we hope that, after reading this book, it will be one that you will remember.
