In compound inequalities we will look at connecting inequalities using some very special words: 'and', and 'or'. We will have to first recognize some subtleties between using both of these words. We will also learn about union and intersection. Once we know more about how to connect them then we can finally get to our compound inequalities and how we can solve these. When using the connector AND, both conditions must be satisfied. When using the connector OR, at least one of the conditions must be satisfied. Some inequalities can be put together into three parts. For these, whatever you do to one piece, you must do to the other two.
*These practice questions are only helpful when you work on them offline on a piece of paper and then use the solution steps function to check your answer.
