Understanding Equalities and Inequalities

Miss Oates introduces a math review video focused on comparing numbers. The video covers how to evaluate models of three-digit numbers to determine if they are greater than, less than, or equal to each other. It explains the use of proper notation for expressing these comparisons and solving related problems. The video includes examples and practice problems to reinforce understanding of the concepts.
