Come on is there anything “basic” in math? Of course there is and hopefully you will find this introduction to inequalities easy. A few things to remember. First inequalities have many (infinite) solutions. Example lets consider x > 3 or “what numbers x are greater than 3”. How many numbers can make this statement true? Clearly all the numbers greater than 3; 4,5,6, etc. Because solutions to inequalities involve sets of numbers we use graphs to express there solutions. The notes below introduce you to the language of graphs of inequalities- pay attention this stuff is very important in algebra.
some key topics that involve basic inequalities:
* real number lines
* linear inequalities
* compound inequalities
