At present, multiple-choice questions (MCQ) and very short answer type questions (VSA) are common features of almost every examination. While they can be solved from first principles, this is often time consuming. In this discussion, some general formulae to solve three common types of arithmetic problems are derived. It is hoped that rather than memorizing these formulae, students will learn to develop and use their own short-cuts as part of their preparation for examinations.
