Understanding Absolute Value Concepts

In this video, Mr. J explains the concept of absolute value, which is the distance a number is from zero. Using a number line, he demonstrates this concept with four examples: -2, 2, -8, and 25. Each example shows how to determine the absolute value by counting the distance from zero, emphasizing that absolute value is always positive. The video concludes with a summary of the concept, reinforcing the use of bars as a symbol for absolute value.
