The first thing that is discussed in this video is the definition of absolute value. Absolute value actually represents distance and is always positive, the symbol of an absolute value is the two bars around the value. Distances are always positive t...hat is why absolute values are always positive. They show absolute value using a number line. Many examples are given, when an equation is between the two bars it means the answer should be in absolute value terms. Then they discuss the opposite of a number. Then they show how to ask what the opposite value is in math equation terms. They explain the opposite of a positive number is like multiplying the number by negative one. They also show the opposite of a positive and negative absolute value. Video is good quality and good for all students as review or initial learning of the concept.
