Proof: Do Line At Unchanged 24

Let's prove the following theorem:

if the following are true:

expression state at time 24 = "iterate_args"
the line at time 24 = 1

then the line at time 25 = 1

Given

1	expression state at time 24 = "iterate_args"
2	the line at time 24 = 1

Proof Table

#	Claim	Reason
1	the line at time (24 + 1) = the line at time 24	if expression state at time 24 = "iterate_args", then the line at time (24 + 1) = the line at time 24 (Iterate Insn (3))
2	the line at time (24 + 1) = 1	if the line at time (24 + 1) = the line at time 24 and the line at time 24 = 1, then the line at time (24 + 1) = 1 (Transitive Property of Equality)
3	24 + 1 = 25	24 + 1 = 25 (Fixed Value Statement)
4	the line at time (24 + 1) = the line at time 25	if 24 + 1 = 25, then the line at time (24 + 1) = the line at time 25 (Substitution)
5	the line at time 25 = 1	if the line at time (24 + 1) = the line at time 25 and the line at time (24 + 1) = 1, then the line at time 25 = 1 (Transitive Property of Equality Variation 2)
