Answers:

Directions (1-3):

1) Answer: A

54 / 27 = 2 [Rule v] 2 * 3 = 6 [Rule ii] R1 = 6

7 + (3)² = 16 [Rule iv] 16 + 12 = 28 [Rule i] R2 = 28

34 / 2 = 17

2) Answer: C

25 – 12 = 13 [Rule iii] 13 – 8 = 5 [Rule iii] R1 = 5

18 + 18 = 36 [Rule i] 36 / 9 = 4 [Rule v] R2 = 4

= 5 * 4 = 20

3) Answer: A

12 * 7 = 84 [Rule ii] 84 + 16 = 100 [Rule i] R1 = 100

67 – 12 = 55 [Rule iii] 55 + (3)² = 64 [Rule iv] R2 = 64

100 – 64 = 36
