In this video they discuss inequalities. They show the greater than/less than symbol. They then explain these symbols using a number line. On a number line the greater than symbol "" "is greater than "or" is to the right of" on the number line. Then they show the "" symbol which is "less than" or "is to the left of" on the number line. They show a number of examples using these symbols. They proceed to the greater than or equal to symbol and the less than or equal to symbol. Once again they do many examples and explain as they do them. Video is good quality and good for all students as review or initial learning of the concept.
