... Before addressing Example C, discuss the following: Inequalities with |A| > b, where b is a positive number, are known as disjunctions and are written as A < –b or A > b. For example, |x| > 5 means the value of the variable x is more than 5 units away from the origin (zero) on a number line. The sol ...
