Understanding Integer Operations and Exponents

The video tutorial explains how to evaluate mathematical expressions by simplifying within parentheses, using integer chips for verification, and simplifying exponents. It covers two expressions: one involving negative numbers and another with positive numbers. The tutorial demonstrates how to convert subtraction into addition, use integer chips for modeling, and verify results using a calculator.
