The text expands on the fundamental concepts of algebra while addressing the needs of students with diverse backgrounds and learning styles. Compound Inequalities is a method to find the variable value for the given compound inequalities. These usually come in two flavors: "or" and "and" inequalities. When dealing with compound inequalities with ‘AND’ statements, only values of the variable that are common in solution sets of both inequalities are considered as answers, while for ‘OR’ statements, as long as even 1 of the inequality is satisfied, the value can be added into the solution set of compound inequality. Do you notice how each of the problems above consist of two inequalities? A compound inequality is a sentence with two inequality statements joined either by the word "or" or by the word "and." "And" indicates that both statements of the compound sentence are true at the same time. The answer are all numbers less than 5 and all numbers greater than 9, so the solution is a union of two intervals $\left<-\infty, 5\right> \cup \left<9, \infty\right>$. When two or more linear inequalities are connected by the word ‘or’, the solution set of the compound inequality problem is obtained by combining the solution(s) of each inequality.
