Section 3: Operations with Signed Numbers
Numbers 7-12 will be given in class (mixed numbers are very difficult to type!)
1) 76 + (-28)=
4) -51 – 64
2) -85 + (-23) =
5) 67 – (-74) =
3) –48 + 37 =
6) -101 – (-44) =
7)
8)
9)
10)
11)
12)
Section 4: Order of Operations:
1) 256 – 46 · 3 – 11=
5) Substitute and Evaluate:
3y3 - 2y2 ÷ 10 + 379 =
y = -5
2) 24 ÷ (6 – 3 · 4) · 13 =
6) Substitute and Evaluate: b = 7 and c = -2
bc2 ÷ (42 – 4b) – 11c =
2
3) 100 - 12 · ¼ + (6)(-2) =
7) Evaluate when a = -8, b = -3, and c = 9
4b3 + ac – ab - 1
c2 – 16b ÷ a + 8a + 2b
Section 5: Simplifying and Solving Equations
1) (6x - 5) + (7x + 7)
2) (6x2 – 5x + 7) + (9x2 – 4x + 8)
3) 4(3x – 5) + 6(4x + 3)
4) 5(6x – 9) – 7(4x – 8)
5)8(3x2 – 4x + 9) + 6(4x2 + 5x – 12)
6) 9(4x2 + 3x – 8) – 7(6x2 – 4x + 10)
7) 6(2x – 5) + 3(3x + 2) = 102
8) 5(5x – 6) = 6(3x + 2)
9) 63 – ¾ x = 27
10) 10(3x + 1) – 6(7x + 2) = 4
11) 8(7x – 12) = 6(5x – 3)
