Description: In this video, we work through a bunch of examples that stretch our thinking on absolute value. What I hope to do in this video is get a little bit more practice thinking about absolute value of the difference of numbers as the distance between those two numbers. So in this first question, we are asked which of the following expressions are equivalent to the absolute value of A minus B. And just as a reminder, the absolute value of A minus B, this expression, this is going to give us the distance between A and B.
