Expressions and Variables - Algebraic Expressions - ALGEBRA I

The video tutorial introduces algebraic expressions, explaining that they consist of numbers, variables, and operations like multiplication, division, addition, or subtraction. The teacher provides examples such as '5x' and '5x + 2' to illustrate these concepts. The session includes an interactive segment with the teacher's daughter, Ezra, to reinforce understanding through examples like 'x times y' and '2 plus p over q'.
