Proof: Get Iterate Expr 17

Let's prove the following theorem:

if the following are true:

expression state at time 17 = "iterate_args"
arguments stack at time 17 = [ [ 9, [ ] ], [ ] ]

then the expression at time 18 = 9

Given

1	expression state at time 17 = "iterate_args"
2	arguments stack at time 17 = [ [ 9, [ ] ], [ ] ]

Proof Table

#	Claim	Reason
1	the expression at time (17 + 1) = 9	if expression state at time 17 = "iterate_args" and arguments stack at time 17 = [ [ 9, [ ] ], [ ] ], then the expression at time (17 + 1) = 9 (Iterate Arguments Expression Property)
2	17 + 1 = 18	17 + 1 = 18 (Fixed Value Statement)
3	the expression at time (17 + 1) = the expression at time 18	if 17 + 1 = 18, then the expression at time (17 + 1) = the expression at time 18 (Substitution)
4	the expression at time 18 = 9	if the expression at time (17 + 1) = the expression at time 18 and the expression at time (17 + 1) = 9, then the expression at time 18 = 9 (Transitive Property of Equality Variation 2)
