Understanding Absolute Value and Distance

The video tutorial explains the concept of absolute value as the distance between two numbers. It explores expressions equivalent to the absolute value of A minus B, using examples to verify equivalence. The tutorial also covers interpreting equations involving absolute values and calculating the area of a rectangle using absolute values. Through various examples, the video emphasizes understanding absolute value in different mathematical contexts.

What does the absolute value of A minus B represent?

• The sum of A and B

• The distance between A and B

• The difference between A and B

• The product of A and B
