Modulus Equations And Inequalities - By Darragh Curran
Modulus Equations And Inequalities Deal With Absolute Values. In Every Day Life We Come Across This When We Talk About The Distance Between Two Places. Newry And Waterford Are Both Approximately 80 Miles From Dublin. This However Does't Make Them The Same Place. They Are Both In Different Directions From Dublin. Newry Is Approximately 80 Miles North And Waterford Approximately 80 Miles South. Saying They Are 80 Miles From Dublin Is Giving The Absolute Value Of Their Distance From Dublin. This Is Analogous To What We Are Dealing With In This Section Of The Course. [View Applet]
