Proof: Get Iterate End Parent 72

Let's prove the following theorem:

if the following are true:

expression state at time 72 = "iterate_args"
arguments stack at time 72 = [ [ ], [ ] ]
parent stack at time 72 = [ __mul__(self.age, 12), [ ] ]

then parent stack at time 73 = [ ]

Given

1	expression state at time 72 = "iterate_args"
2	arguments stack at time 72 = [ [ ], [ ] ]
3	parent stack at time 72 = [ `__mul__(self.age, 12)`, [ ] ]

Proof Table

#	Claim	Reason
1	parent stack at time (72 + 1) = [ ]	if expression state at time 72 = "iterate_args" and arguments stack at time 72 = [ [ ], [ ] ] and parent stack at time 72 = [ `__mul__(self.age, 12)`, [ ] ], then parent stack at time (72 + 1) = [ ] (Iterate Args Empty (3))
2	72 + 1 = 73	72 + 1 = 73 (Fixed Value Statement)
3	parent stack at time (72 + 1) = parent stack at time 73	if 72 + 1 = 73, then parent stack at time (72 + 1) = parent stack at time 73 (Substitution)
4	parent stack at time 73 = [ ]	if parent stack at time (72 + 1) = parent stack at time 73 and parent stack at time (72 + 1) = [ ], then parent stack at time 73 = [ ] (Transitive Property of Equality Variation 2)
