Introduction to the mathematics section

Mathematics problems are presented as multiple-choice questions. Each of the questions is followed by five answer choices. The paper-based and computer-based CBEST require that you select the best answer from among the five choices. Read the directions carefully before you answer each question. Most questions appear as short word problems or graph illustrations.

The sample question that follows illustrates a computer-based mathematics question.

Sample Computer-Based Question

Note: The computer-based exam does not label answer choices with letters. This study guide uses letters A, B, C, D, and E for clarity.

As you read and evaluate the question, circle or write down key words to make sure you understand the question. The question asks you to find the cost of the accessories, not the cost of the cell phone. This problem can be worked by using trial and error or by using algebra.

Method 1:Trial and Error. Remember, the answer choices represent the cost of the accessories.

Cost of accessories + cost of cell phone = $100 (recall that the accessories are $20 more than the cell phone)

Method 2: Algebra. Start by either representing the cost of the cell phone or the cost of the accessories. Suppose x = the cost of the cell phone, and then x + 20 = the cost of the accessories since the accessories cost $20 more than the cell phone. The combined cost is $100, so

Notice the x is the cost of the cell phone, and the question asks for the cost of the accessories. Because the accessories cost $20 more than the phone, the answer is $60, choice E. Suppose x = the cost of the accessories, and then x — 20 = cost of the cell phone. Then the equation would have been

Since the x here represents the cost of the accessories, you have the correct answer, choice E.
