Sommario/riassunto

Most wastewater operators cite mathematics as the subject giving them the most difficulty on their operator certification exams, as well as on the job. This math study text is designed to help wastewater operators improve their math skills, pass certification exams, perform their jobs better, and advance their careers. The guide provides examples of a variety of different problems that will be encounted both on Grades 3 and 4 certification exams and on the job. Each problem is presented with easily followed steps and comments to facilitate understanding. Tests with answers are included after each grade level to help you determine where your strengths and weaknesses are. Appendices
