Proof: Do Class Defs At Unchanged 8

Let's prove the following theorem:

if the following are true:

expression state at time 8 = "return"
Class Map at time 8 = [ ]

then Class Map at time 9 = [ ]

Given

1	expression state at time 8 = "return"
2	Class Map at time 8 = [ ]

Proof Table

#	Claim	Reason
1	Class Map at time (8 + 1) = Class Map at time 8	if expression state at time 8 = "return", then Class Map at time (8 + 1) = Class Map at time 8 (Return (11))
2	Class Map at time (8 + 1) = [ ]	if Class Map at time (8 + 1) = Class Map at time 8 and Class Map at time 8 = [ ], then Class Map at time (8 + 1) = [ ] (Transitive Property of Equality)
3	8 + 1 = 9	8 + 1 = 9 (Fixed Value Statement)
4	Class Map at time (8 + 1) = Class Map at time 9	if 8 + 1 = 9, then Class Map at time (8 + 1) = Class Map at time 9 (Substitution)
5	Class Map at time 9 = [ ]	if Class Map at time (8 + 1) = Class Map at time 9 and Class Map at time (8 + 1) = [ ], then Class Map at time 9 = [ ] (Transitive Property of Equality Variation 2)
