Exploring Operations with Rational Numbers

This video tutorial explains the order of operations for rational numbers using the BEDMAS rule, which stands for Brackets, Exponents, Division and Multiplication (from left to right), and Addition and Subtraction (from left to right). The tutorial provides two examples to demonstrate the application of these rules. In the first example, the focus is on division and multiplication, while the second example includes simplification within brackets and the use of exponents. The video emphasizes the importance of following the correct order to achieve accurate results.
