Understanding Terms in Mathematical Expressions

The video tutorial explains how terms in mathematical expressions are separated by plus and minus signs, while multiplication and division do not separate terms. It provides examples to illustrate these concepts, showing how to identify the number of terms in various expressions. The tutorial also discusses coefficients and analyzes complex expressions, concluding with a summary of the key points.
