Lesson Summary:
In this lesson, we review simplifying numerical expressions using the order of operations. We learn that when we have a fraction, we need to simplify the numerator and denominator separately before canceling or reducing. Following the order of operations, we simplify within parentheses or any grouping symbols, then exponents, then multiplication and division, and finally, addition and subtraction. Additionally, we see examples of reducing fractions and the different ways to cancel common factors.
