1.                                         3

2. 3.9^2=15.21 -0.21=       15

3.  22/5.5=4 +5.5=            9.5

4.                                       2

5. 4x.5=2+0.8=                2.8

6. 6.4+3.6=                   10

7. 3^3=27-1.7=              25.3

8. 6.5/5=                         1.3

9. 3x5=15-3.5=               11.5

10. 41.32/2=20.66-5.45=      15.21

11. 3.79-0.19=                     3.6

1. C. 7.5 / 2.5 = 3
2. E. 3.9 x 3.9 = 15.21 - 0.21 = 15
3. B. 22/5.5 = 4 + 5.5 = 9.5
4. D. 7 • 0.3 = 2.1 - 0.1 = 2
5. H. 4 x 0.5 = 2 + 0.8 = 2.8
6. F. 6.4 + 3.6 = 10
7. J. 3 cubed = 27 - 1.7 = 25.3
8. K 6.5 / 5 = 1.3
9. A 3(5) - 3.5 = 15 -3.5 = 11.5
10. I 41.32/2 = 20.66 - 5.45 = 15.21
11. G. 3.79 - 0.19 = 3.6
12. L. 0.09 + 6(0.6) = 0.09 + 3.6 = 3.69
