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 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)
