Identifying Terms and Parts of Expressions

This video tutorial explains expressions, focusing on numerical and algebraic types. It defines terms as parts of expressions, which can be numbers, variables, or products of both. The video also covers identifying terms by looking for parts separated by addition or subtraction. It further breaks down expressions into variables, coefficients, constants, and exponents, and explains operations like sum, difference, and product. The tutorial concludes with a recap and practice exercise to reinforce learning.
