    Section One
    Interval Notation and graph:

    50 - The set of real numbers less than or equal to - 4

    94 - Which of the following integers has an absolute value greater than 1
    -4,-3,-2,-1,0,1,2,3,4

    100- The interval notation for the following:
    X-------0
    -50 -40 -30 -20 -10 0 10 20 30
    | | | | | | | | |

    110 - Suppose that "a" is a negative number. Which of the following is a positive number? Explain your answer.

    a) -a b) |-a| c) -|a| d)-(-a) e)-|-a|

    Section Two
    18 - Build up

    86 - Convert to its other two forms:

    104 - Perform the indicated operations:

    Section Three
    36 - Solve -9-(-2.3) = -9 + (?)

    66 - Perform the indicated operation: -19-13

    70 - Perform the indicated operation: 15 + (-39)

    90 - Solve: 13 + (?) = -4

    Section Four
    48 - Perform the Operation: (-8)(-6)

    62 - Perform the operation:

    76 - Solve: -48 (?) = 6

    Section Five
    90 - Evaluate: [3 - (2 - 4)] [3 + |2 - 4| ]

    116 - Evaluate: 8 - 3 |5 - 4 + 1 |

    Section Six
    54 - Evaluate with a = -1, b = 2, and c = -3: (a-c)(a+c)

    76 - Is the given number a solution to the equation: 5, 3x + 7 = 2x - 1

    Section Seven
    24 - Rewrite the product: y(y * 5)(wy)

    40 - Remove the parenthesis: -3 (6 - p)

    Section Eight
    36 Combine like terms if possible:

    96 Simplify by combining like terms: 2a(a-5)+4(a-5)

    114 Simplify:
