This states graph the solution of an inequality on a number line. When we talk about the solution we're talking about what satisfies that statement. Here is a vedio explaining how to do it: http://www.youtube.com/watch?v=y81YtBL1Q40&feature=player_detailpage. Sometimes the statements have and or the word or in it this is called a compound inequality. http://www.youtube.com/watch?v=xOPFNDmBCKU&feature=player_detailpage. Now what yo have just seen is an example using or and is much different as I will show you. Say if they give you x<3 and x>o here's how you do it:
We connected them because the any where that we shaded satisfies the statements. We have a dark circle over zero because it has an equal to sign under it. There is a open circle over 3 because it does not have and equal sign and to show it is not part of the solution set.

Your inequality signs are important to remember here.
