Absolute Values<\/h1>\n

Objective<\/h4>\n

In this lesson, you will learn about absolute value for real numbers.<\/p>\n

Previously Covered:<\/h4>\n

What is absolute value?<\/p>\n

The absolute\u00a0value<\/abbr> of a number is its distance from zero on a number line.<\/p>\n

The notation for “the absolute value of a,<\/em>” where a<\/em> is some real number, is .\u00a0The bars tell you to find the absolute value of the number inside.<\/p>\n

\n

How does absolute value fit in?<\/h3>\n

Absolute value shows the distance a number is from zero on a\u00a0number line.<\/p>\n

\n

Question<\/h4>\n

Which of the following numbers is closest to zero?<\/p>\n

    \n
  1. <\/li>\n
  2. 0.25 <\/span><\/li>\n
  3. – 0.3
    \n<\/span><\/li>\n
  4. <\/li>\n<\/ol>\n

    Reveal Answer <\/a><\/p>\n

    \n

    The correct answer is A. Find the absolute value of each\u00a0number. The choice with the smallest absolute value will be\u00a0closest to zero. Choice A has the smallest absolute value, 0.2.\u00a0Choices B and D have the same absolute value, 0.25.<\/p>\n<\/div>\n<\/section>\n

    How do I represent an absolute value on a number line?<\/h3>\n

    To represent a number on the number line, plot all points with\u00a0the absolute value of the given number.<\/p>\n

    Question<\/h4>\n
    \n

    Which number line represents the graph of\u00a0\"graphics5\"\u00a0?<\/p>\n

      \n
    1. \"number<\/li>\n
    2. \"number<\/li>\n
    3. \"number<\/li>\n
    4. \"number<\/li>\n<\/ol>\n<\/div>\n

      Reveal Answer <\/a><\/p>\n

      \n

      The correct answer is D. The absolute value of \u20133 is 3.\u00a0The number line must show a point at 3.<\/p>\n<\/div>\n<\/section>\n<\/section>\n
