Measurement basic mathematical skills

This section is a review of basic mathematical skills. For success on the GRE, it is important to master these skills. Because the GRE measures your ability to reason rather than calculate, most of this section is devoted to concepts rather than arithmetic drills. Be sure to review all the topics before moving on to the algebra section. 

NEW BASIC MATH SKILLS APPENDIX To aid the flow of introductory chemistry material in Chapter I, a review of topics in basic mathematics skills, including scientific notation and use of significant figures, with numerous examples, now appears in Appendix A. Related exercises remain in the Measurements and Calculations section at the end of Chapter 1. 

In addition to accomplishing these goals, a reader is exposed to background information on units and measurements of physical properties, basic laws about the behavior of gas, liquids, and solids, and some basic mathematical tools. Although communication and programming skills are essential for both students and professionals, assimilation of material in this book does not require mastery of either. Other objectives that an instructor may want to include in a course, such as information about professional activities, developing a professional attitude, establish-... 

Science, mathematics, and technology are interconnected. Teaching Chemistry incorporates the other sciences as well as other disciplines, such as mathematics. For example, graphs and charts are frequently used to record and analyze data. On a daily basis, we are surrounded with mathematics in the ability to make various measurements of mass and size, in the conversions betweens the numerous units, and in tabulating amounts of materials. Beyond these basic skills, mathematical and algebraic skills are used in a plethora of chemical calculations from determining the percent composition of elements in a compound to estimating the mass of reactants needed in a reaction.
