    Comparing and ordering integers Comparing and ordering integers Presentation Transcript

    • *An integer is the set of whole numbers andtheir opposites.*In other words, integers are positive (+) andnegative (-) whole numbers.*Examples of integers include:12 7 -10 -125 18 -30,843
    • *Fractions and decimals are NOT integers. Thoseare rational numbers.*Integers are whole numbers!
    • *Let’s look at integers on a number line.*Plot the integers 1, -9, -4, and 7 on the numberline.
    • Compare the following integers. Use <, =, or >.Try drawing a number line to help you visualize the integers!0 ___ 10 -5 ___ 15 5 ___ -150 ___ -20 -8 ___ 8 -6 ___ 6
    • Order the following integers from least to greatest-4 3 2 0
    • For this problem, we are working with -4, 3, 2, 0
    • *Least to greatest is left to right.*Greatest to least is right to left.*Our answer should be -4, 0, 2, 3.
    • *The absolute value of a number is distance itis away from zero on the number line.*We show absolute value like this: |-2|*Absolute values are always positive becausethe signify the distance from zero on thenumber line!*|-2| = 2
    • 1. Order these temperatures from least to greatest:0°F, 115°F, -15°F, -32°F, -40°F, 113°F2. Compare. Use <, =, or >.0 ___ -20 |-8| ___ 8 -6 ___ 63. Estimate values for points A – E.A B C D E
