Exploring Adding and Subtracting Rational Expressions

The video tutorial introduces the concept of the order of operations in mathematics, using a mnemonic sentence to help remember the sequence: groupings, exponents, multiplication and division, and addition and subtraction. It explains each step with examples, demonstrating how to solve problems correctly by following the order. The tutorial includes practice problems to reinforce learning and concludes by revisiting an initial problem to show the correct solution.
