Exploring Parts of an Expression

The video tutorial introduces the concept of mathematical expressions, explaining their components such as terms, variables, coefficients, and constants. It emphasizes that expressions do not contain equal signs and provides examples and non-examples. The tutorial also includes a practice section where viewers match terms with their definitions. The session concludes with a review and acknowledgments.

What is NOT a characteristic of an expression?
