Proof: Do Line At Unchanged 32

Let's prove the following theorem:

if the following are true:

expression state at time 32 = "call_function_begin"
the line at time 32 = 3

then the line at time 33 = 3

Given

1	expression state at time 32 = "call_function_begin"
2	the line at time 32 = 3

Proof Table

#	Claim	Reason
1	the line at time (32 + 1) = the line at time 32	if expression state at time 32 = "call_function_begin", then the line at time (32 + 1) = the line at time 32 (Assign Parent (6))
2	the line at time (32 + 1) = 3	if the line at time (32 + 1) = the line at time 32 and the line at time 32 = 3, then the line at time (32 + 1) = 3 (Transitive Property of Equality)
3	32 + 1 = 33	32 + 1 = 33 (Fixed Value Statement)
4	the line at time (32 + 1) = the line at time 33	if 32 + 1 = 33, then the line at time (32 + 1) = the line at time 33 (Substitution)
5	the line at time 33 = 3	if the line at time (32 + 1) = the line at time 33 and the line at time (32 + 1) = 3, then the line at time 33 = 3 (Transitive Property of Equality Variation 2)
