Proof: Do Tab At Unchanged 52

Let's prove the following theorem:

if the following are true:

expression state at time 52 = "call_function_begin"
the tab at time 52 = 2

then the tab at time 53 = 2

Given

1	expression state at time 52 = "call_function_begin"
2	the tab at time 52 = 2

Proof Table

#	Claim	Reason
1	the tab at time (52 + 1) = the tab at time 52	if expression state at time 52 = "call_function_begin", then the tab at time (52 + 1) = the tab at time 52 (Assign Parent (7))
2	the tab at time (52 + 1) = 2	if the tab at time (52 + 1) = the tab at time 52 and the tab at time 52 = 2, then the tab at time (52 + 1) = 2 (Transitive Property of Equality)
3	52 + 1 = 53	52 + 1 = 53 (Fixed Value Statement)
4	the tab at time (52 + 1) = the tab at time 53	if 52 + 1 = 53, then the tab at time (52 + 1) = the tab at time 53 (Substitution)
5	the tab at time 53 = 2	if the tab at time (52 + 1) = the tab at time 53 and the tab at time (52 + 1) = 2, then the tab at time 53 = 2 (Transitive Property of Equality Variation 2)
