    Study Notes

    Counting Backwards

    • When counting backwards from 6 to -3, the correct order is: 6, 5, 4, 3, 2, 1, 0, -1, -2, -3

    Basic Algebra

    • 5 + (-8) = 5 - 8 = -3
    • A calculation results in a negative answer when a positive number is subtracted by a larger number, or when a negative number is added to a positive number
    • Subtracting a negative number is equivalent to adding a positive number

    Negative Numbers

    • When counting backwards from zero using negative numbers, the next number after -12 is -13

    Algebraic Expressions

    • In the expression x8, the base is x and the exponent is 8
    • In the expression b3, the base is b and the exponent is 3
    • The numerical coefficient of the expression 5x is 5

    Evaluating Expressions

    • If p = 2 and q = 5, then 2p + q2 = 2(2) + 5^2 = 4 + 25 = 29

    Domain and Range

    • The values of 2t over the domain {3, 4, 7, 8} are 2(3) = 6, 2(4) = 8, 2(7) = 14, and 2(8) = 16
