Twenty to thirty percent of the questions in the math section of the GED test will be from this category. These questions will test your basic ability to work with numbers, especially in hypothetical real life scenarios. You may encounter questions about how many gallons of gas it would take to drive a certain distance or what a 15 percent tip on a restaurant bill would be. The questions will be multiple choice.
The measurement and geometry section of the GED test will require you to be able to solve problems using spacial visualization, graphs and measurements. You will need to plot specific points on graphs, determine the area, circumference and volume of shapes, and perform other similar tasks. Knowing the Pythagorean theorem will be helpful during this section of the test, as will knowing the formulas for calculating area, volume, circumference, diameter and similar measurements.
The questions relating to data analysis, statistics and probability will require you to understand and interpret data. You may have to compare information in two or more graphs, for example, or make a logical prediction based on the given information. This section will contain quite a few graphs, charts, tables and other forms of visual data. You will also need to know the difference between the mean, median and mode when facing this section of the GED.
This section of the GED's mathematics portion will require you to deal with problems in which letters replace numbers. You will need to solve various problems, including ones that contain linear and quadratic expressions. This section will also test your understanding of squares and square roots. Some of the problems in this section will provide the equation for you to solve, while others will simply provide information from which you must create your own equation and solution.
