Ch 33: Interpreting Numbers, Data & Expressions

About This Chapter

Before you take your upcoming assessment, use this chapter to get a quick review on interpreting numbers, data, and expressions. Recap on these fundamental mathematical concepts and principles by reading the lessons and watching the videos.

Interpreting Numbers, Data & Expressions - Chapter Summary

If you need to dust off the cobwebs in your memory about interpreting numbers, data, and expressions, then open up the lessons in this chapter. Our instructors go over definitions first to jog your memory, then they discuss examples that highlight these concepts. Within this chapter, you will find lessons that review the following:

  • Reading graphs, charts, and tables
  • Deriving meaning from graphical representations of data
  • Defining a mathematics equation
  • Steps for setting up and solving math problems
  • Proving that relationships are algebraic expressions
  • Identifying the mathematical order of operations
  • Examining algebraic expressions

As you look through our study materials, you may have noticed that the timestamp on each of our lessons seems a little short, but you should know that we have designed shorter lessons on purpose. Longer lessons don't always help people learn, and in fact they often lead to burnout. With our shorter lessons, there's only enough time to focus on one topic. By giving you the most pertinent information about a single topic, we know you are more likely to retain the details and be able to recall them during testing conditions.

With so many lessons to choose from, you may feel lost. Luckily, our lessons are well-labeled, so you can find exactly what you want to study without any frustration. Since our lessons are short, you can fit several throughout your day. After all, the more lessons you complete, the more excited you will become about studying. If you are excited about studying, then that makes you more motivated to do well on your assessment.
