ACT Math Problems for Algebra

Our algebra equations section shows you how to solve pre-algebra, elementary algebra, and intermediate algebra questions on the ACT math test.

The algebra questions on the exam cover basic mathematical concepts such as:

  • mean (arithmetic average)
  • median
  • operations with decimals
  • percentages
  • fractions
  • absolute values
  • square roots
  • estimations
  • rounding
  • approximations

You will encounter combinations of these concepts in certain ACT math problems in the intermediate algebra questions on the test.

So you will need more than one type of math formula to solve these types of questions.

For instance, you may see a question that has a fraction which contains another fraction or a decimal in its numerator or denominator.

Another common type of problem is where an erroneous result is given.

Then you have to use the data provided in order to correct the result.

An example of this would be the type of practical algebra problem in which the average grade has been calculated for a class, but the score for one student was omitted.

You will be given the erroneous average and the omitted score and then you will have to calculate the correct average.

ACT Math Problems for Coordinate Geometry and Plane Geometry

The coordinate geometry and plane geometry questions section gives you the math formulas that you need in order to calculate coordinate geometry problems, such as midpoints, slope, and distance.

Our geometry problems page also gives you common formulas for plane geometry, in other words, for calculations on figures like circles, triangles, squares, rectangles, and cones.

In the plane geometry formulas section, you will see the equations that you need to determine the measurement of the circumference of circles, as well as the area, angles, perimeter, and volume of various geometric figures.

ACT Math Problems for Trigonometry

You will also see the equations that you need in order to calculate trigonometric functions on the math test.

The trigonometry section illustrates the concepts of sine, cosine, and tangent and gives you the math formulas that you need for these trigonometric relationships.
