Identifying Equations and Expressions

The video tutorial explains the difference between equations and expressions, emphasizing that equations contain an equal sign while expressions do not. It provides examples to illustrate how to identify equations using keywords like 'is' followed by a number. The tutorial concludes with tips for recognizing equations, such as looking for a number at the end of a sentence.
