Subtracting Negative Numbers Using Integer Chips

This video tutorial teaches how to subtract integers using integer chips. It begins with an introduction to integer subtraction and explains how integers can be modeled with yellow and red chips, representing positive and negative numbers, respectively. The concept of zero pairs is introduced, where opposite quantities cancel each other out. The video then reviews the rules for adding integers with like and different signs, emphasizing the importance of zero pairs. Several examples are provided to illustrate integer subtraction, including scenarios involving debt and spending. Advanced problems are also covered, demonstrating the use of zero pairs to solve complex subtraction problems.
