What's the answer hidden in the puzzle below?
3 m 2 m 1 = 0
9 m 3 m 2 m 1 = 3
1 p 5 m 0 p 5 = 1
(1 p 5)(8)(1 p 5)(1 p 5) = 27
(3 p 5)(4) = 14
(4 p 5)(8) = 36
10 m 2 m 3 p 5 m 4 = 1/2
(1 p 2)(5)(1 p 5) m 7 = 2
7 p 5 m 6 = 3/2
8 m 4 = 4
(3 p 2)(5)(2 p 5) = 40
17 m 9 m 2 m 1 = 5
16 m 13 p 5 = 5/2
(2 p 5)(8)(1 p 5)(1 p 4) = 42
