Proof: Do Tab At Unchanged 14

Let's prove the following theorem:

if the following are true:

expression state at time 14 = "call_function_begin"
the tab at time 14 = 0

then the tab at time 15 = 0

Given

1	expression state at time 14 = "call_function_begin"
2	the tab at time 14 = 0

Proof Table

#	Claim	Reason
1	the tab at time (14 + 1) = the tab at time 14	if expression state at time 14 = "call_function_begin", then the tab at time (14 + 1) = the tab at time 14 (Assign Parent (7))
2	the tab at time (14 + 1) = 0	if the tab at time (14 + 1) = the tab at time 14 and the tab at time 14 = 0, then the tab at time (14 + 1) = 0 (Transitive Property of Equality)
3	14 + 1 = 15	14 + 1 = 15 (Fixed Value Statement)
4	the tab at time (14 + 1) = the tab at time 15	if 14 + 1 = 15, then the tab at time (14 + 1) = the tab at time 15 (Substitution)
5	the tab at time 15 = 0	if the tab at time (14 + 1) = the tab at time 15 and the tab at time (14 + 1) = 0, then the tab at time 15 = 0 (Transitive Property of Equality Variation 2)
