Real number symbols

Purplemath. You never know when set notation is going to pop up. Usually, you'll see it when you learn about solving inequalities, because for some reason saying " x < 3 " isn't good enough, so instead they'll want you to phrase the answer as "the solution set is { x | x is a real number and x < 3 } ". How this adds anything to the student's ... .
