Mathematical Concepts and Problem Solving

Dr. Peter Price introduces a video focused on extended multiplication and division, specifically multiplying and dividing by three. The video is based on a book designed for revision, aiming to help students become familiar with slightly more complex forms of these operations. The video includes examples of straightforward multiplication and division questions, as well as problems involving unit fractions, where multiplying by a fraction with a numerator of one is equivalent to dividing by the denominator. The video concludes with encouragement for students to practice and improve their speed and accuracy.
