Proof: Get Iterate Expr 35

Let's prove the following theorem:

if the following are true:

expression state at time 35 = "iterate_args"
arguments stack at time 35 = [ [ "Spain", [ ] ], [ ] ]

then the expression at time 36 = "Spain"

Given

1	expression state at time 35 = "iterate_args"
2	arguments stack at time 35 = [ [ "Spain", [ ] ], [ ] ]

Proof Table

#	Claim	Reason
1	the expression at time (35 + 1) = "Spain"	if expression state at time 35 = "iterate_args" and arguments stack at time 35 = [ [ "Spain", [ ] ], [ ] ], then the expression at time (35 + 1) = "Spain" (Iterate Arguments Expression Property)
2	35 + 1 = 36	35 + 1 = 36 (Fixed Value Statement)
3	the expression at time (35 + 1) = the expression at time 36	if 35 + 1 = 36, then the expression at time (35 + 1) = the expression at time 36 (Substitution)
4	the expression at time 36 = "Spain"	if the expression at time (35 + 1) = the expression at time 36 and the expression at time (35 + 1) = "Spain", then the expression at time 36 = "Spain" (Transitive Property of Equality Variation 2)
