Lesson Summary:

In this Elementary Algebra Review lesson, students will learn how to simplify numerical expressions using order of operations, and evaluate variable expressions by plugging in given values. The lesson includes six problems that cover a range of concepts, such as subtraction, division, and multiplication. Each problem is explained step-by-step, and students are encouraged to write each number as an integer or reduced fraction, rather than a decimal. By the end of the lesson, students will have strengthened their algebra skills in a practical, real-world way.
