    Study Notes

    Numerical Representations Unit

    Rational Numbers

    • A list of rational numbers can be ordered from greatest to least.
    • Rational numbers can be represented as decimals, percentages, or fractions.

    Absolute Value

    • The absolute value of a temperature is the distance from zero.
    • Example: The absolute value of -9°C is 9.

    Number Lines

    • A number line can be used to represent rational numbers.
    • Numbers to the left of zero are negative, while numbers to the right of zero are positive.
    • Example: -1.5 is located to the left of zero on a number line.

    Ordering Rational Numbers

    • Rational numbers can be ordered from least to greatest.
    • Example: -66, -6.65, -6, 5 can be ordered from least to greatest.

    Integers

    • Integers are whole numbers, either positive, negative, or zero.
    • Example: -9, -7, -4, -2, 1, 5 are integers.

    Classifying Numbers

    • Numbers can be classified as rational numbers, integers, or whole numbers.
    • Example: -29 can be classified as an integer.
