Ch 2: Praxis I Math: The Real Number System

Let us help you learn about the real number system. Video lessons and self-assessment quizzes are the teaching tools you'll use to get ready for the Praxis I Math skills test.

Praxis I Math: The Real Number System

You'll learn about the different types of numbers, arithmetic with whole numbers, arithmetic calculations with signed numbers and reducing and rebuilding fractions as you work your way through the lessons in this chapter. Video lesson topics also include:

• Finding the least common denominator
• Ordering and comparing fractions
• Changing between improper fraction and mixed number form
• Adding and subtracting like and unlike fractions and mixed numbers
• Multiplying and dividing fractions and mixed numbers
• Practicing with fractions and mixed number arithmetic
• Finding the greatest common factor
• Finding the least common multiple
• Understanding irrational numbers and approximating them by rational numbers
• Finding the greatest common factor

Video instructors will give you a full breakdown of each lesson as they offer advice on how the information they teach can best be used on the Praxis I Math test. To make sure that you're fully prepared for the test and so the lessons remain interesting, a variety of learning approaches will be applied throughout the chapter.

Objectives of the Real Number System Course

Measuring the mathematical skills and concepts that a college-educated adult might need is the main objective of the Praxis I Math test. The real number system is part of the number and operations portion of the test, which is roughly 32.5% of the skills test. As you complete the lesson's self-assessment quizzes, you'll see how questions are formatted on the Praxis in addition to getting an idea of how familiar you are with the testing methods you're learning.

Typically, there are 15 multiple choice questions about number and operations on the skills test. You'll have 75 minutes to complete the full exam, but you won't be allowed to use a calculator.
