In a stack $s$ , TIM is equivalent to s.push(s.pop() * s.pop()) and SUM is equivalent to s.push(s.pop() + s.pop()). What will the following stack machine evaluate the operations as?

PUSH 1   
PUSH 2   
PUSH 3   
PUSH 4   
PUSH 5   
SUM   
TIM   
SUM   
TIM

29 = \left( ( 5 + 4 ) \times 3 + 2 \right) \times 1

19 = 1 \times 2 + 3 \times 4 + 5

27 = 5 \times 4 + 3 \times 2 + 1

65 = \left( 1 + 2 ) \times 3 + 4 \right) \times 5
