Understanding Absolute Values

In this video, Mr. J explains how to compare absolute values, which represent the distance a number is from zero. The video covers four comparisons: -3 vs. 2, -4 vs. 4, -8 vs. -2, and 7 vs. -12. Using a number line, Mr. J demonstrates how to determine which absolute value is greater or if they are equal. The video emphasizes understanding the concept of distance from zero, regardless of whether the numbers are positive or negative.
