Proof: Get Iterate Expr 69

Let's prove the following theorem:

if the following are true:

expression state at time 69 = "iterate_args"
arguments stack at time 69 = [ [ 12, [ ] ], [ ] ]

then the expression at time 70 = 12

Given

1	expression state at time 69 = "iterate_args"
2	arguments stack at time 69 = [ [ 12, [ ] ], [ ] ]

Proof Table

#	Claim	Reason
1	the expression at time (69 + 1) = 12	if expression state at time 69 = "iterate_args" and arguments stack at time 69 = [ [ 12, [ ] ], [ ] ], then the expression at time (69 + 1) = 12 (Iterate Arguments Expression Property)
2	69 + 1 = 70	69 + 1 = 70 (Fixed Value Statement)
3	the expression at time (69 + 1) = the expression at time 70	if 69 + 1 = 70, then the expression at time (69 + 1) = the expression at time 70 (Substitution)
4	the expression at time 70 = 12	if the expression at time (69 + 1) = the expression at time 70 and the expression at time (69 + 1) = 12, then the expression at time 70 = 12 (Transitive Property of Equality Variation 2)
