Understanding Integers and Absolute Values

Mr. Peterson introduces integers, explaining their properties and how to place them on a number line. He covers ordering and comparing integers, including the use of greater than, less than, and equal to signs. The concept of absolute value is explained as the distance from zero, and methods to find the opposite of an integer are demonstrated. Real-life applications of integers, such as in golf scores, sea levels, and temperatures, are discussed.
