Adding and Subtracting Integers with Chips

The video tutorial from MooMooMath demonstrates how to add and subtract integers using visual aids like chips, represented by nickels and pennies. The instructor explains the concept of zero pairs, where a positive and a negative cancel each other out. Through several examples, the video illustrates how to handle both addition and subtraction of integers, including converting subtraction problems into addition problems for easier computation. The tutorial concludes with a summary of the methods and encourages viewers to subscribe for more math content.
