Chapter 14
Applied Arithmetic
In this chapter, we go over more arithmetic problems involving setup problems, averages, ratios and proportions, rate problems, charts and graphs, exponents, radicals, scientific notation, probability, and counting.
Now we're going to show you some additional arithmetic concepts that build on the ideas you've already learned in the last chapter. As in that chapter, we'll introduce a concept first and then give you some sample GED® questions followed by a short drill. At the end of the chapter, you'll find a big drill that mixes and matches all the different concepts. These are the subjects we'll cover.
Setup problems
Mean, median, mode, range, and weighted mean
Ratios and proportions
Rate problems
Charts and graphs
Exponents and square roots
Scientific notation
Probability
Counting
SETUP PROBLEMS
Wouldn't it be interesting if a test question asked you to do the entire setup of a problem, but didn't want you to actually solve it? In fact, if you go on to college, you will find that this is often exactly what college math tests are like. College professors are much more interested in seeing how you think than how careful you are with your addition and subtraction.
