Lesson Summary:

In this lesson, students learn how to evaluate basic algebraic expressions without negative numbers. By replacing variables with specified numbers and following the order of operations, students can simplify expressions and find their value. The lesson includes examples of how to tackle these types of problems, and emphasizes that there are different ways to approach them, such as rewriting exponents before replacing variables.

    This is a very basic math tutorial on how to evaluate basic Algebraic expressions given numerical values of variables. Variables are simply replaced by their values and the expressions are evaluated. Every step is shown in detail in each of six example problems.
