Mastering Order of Operations with Fractions

This video tutorial covers the order of operations with a focus on fractions. It reviews key fraction rules, such as the need for common denominators when adding or subtracting, and the 'keep, change, flip' method for dividing fractions. The tutorial includes five examples demonstrating these concepts, including multiplying fractions, subtracting mixed numbers, using exponents with fractions, and performing division and subtraction. Each example is broken down step-by-step to reinforce understanding of the order of operations and fraction rules.
