Comparing Numerical Expressions without Evaluation

The video tutorial teaches how to compare numerical expressions without evaluating them by reasoning about operations. It explains the concepts of multiplication and addition, and how to model expressions to understand their comparisons. The lesson emphasizes understanding the operations rather than calculating exact values, using examples to illustrate the differences between expressions.
