MORE INFO

The ACT Math test consists of 60 questions that must be answered within the 60-minute time limit. All of the math questions are five-choice, multiple-choice questions. These questions draw from six areas of math that most students have covered by the end of their 11th grade year: pre-algebra, elementary algebra, intermediate algebra, coordinate geometry, plane geometry, and trigonometry. Below you can find more detailed information about the specific skills these questions test, as well as sample ACT Math questions and answer explanations.

**Sample ACT Math Test Questions**

To give you a better feel for the format and content of the ACT Math test, let's take a look at a few sample ACT Math questions.

*Pre-Algebra Question: Mean, Median, and Mode*

70, 80, 50, 20, 80, 30, 80

Seven students took an art history exam. Their scores are listed above. Which of the following statements regarding the scores is true?

I. The average (arithmetic mean) is greater than 70.

II. The mode is greater than 70.

III. The median is greater than 70.

A. |
None |

B. |
II only |

C. |
I and II only |

D. |
II and III only |

E. |
I, II, and III |

** Answer: **First, find the average (arithmetic mean) of the test scores. Mean = (70 + 80 + 50 + 20 + 80 + 30 + 80)/7 = 58.57. 58.57 is not greater than 70. Therefore, item I. is not true, and we can eliminate choices C and E. Second, find the median of the test scores. To do so, put the test scores in ascending or descending order: 20, 30, 50, 70, 80, 80, 80. The median (the number in the middle) is 70. Therefore, item III. is not true, and we can eliminate choice D. Third, find the mode of the test scores (the number that appears most frequently): 80. Therefore, item II. is true. Choice B is the correct answer.

*Plane Geometry Question: Plane Figures and Angles*

If line *m* intersects the square as shown, what must the value of *x* + *y* be?

A. |
45 |

B. |
75 |

C. |
85 |

D. |
90 |

E. |
180 |

** Answer: **The sides of a square are parallel, so line
