Proof: Do Variables At Unchanged 2

Let's prove the following theorem:

if the following are true:

expression state at time 2 = "iterate_args"
Variables Map at time 2 = [ ]

then Variables Map at time 3 = [ ]

Proof:

Given

1	expression state at time 2 = "iterate_args"
2	Variables Map at time 2 = [ ]

Proof Table

#	Claim	Reason
1	Variables Map at time (2 + 1) = Variables Map at time 2	if expression state at time 2 = "iterate_args", then Variables Map at time (2 + 1) = Variables Map at time 2 (Iterate Insn (2))
2	Variables Map at time (2 + 1) = [ ]	if Variables Map at time (2 + 1) = Variables Map at time 2 and Variables Map at time 2 = [ ], then Variables Map at time (2 + 1) = [ ] (Transitive Property of Equality)
3	2 + 1 = 3	2 + 1 = 3 (Fixed Value Statement)
4	Variables Map at time (2 + 1) = Variables Map at time 3	if 2 + 1 = 3, then Variables Map at time (2 + 1) = Variables Map at time 3 (Substitution)
5	Variables Map at time 3 = [ ]	if Variables Map at time (2 + 1) = Variables Map at time 3 and Variables Map at time (2 + 1) = [ ], then Variables Map at time 3 = [ ] (Transitive Property of Equality Variation 2)
