Proof: Do Class Defs At Unchanged 16

Let's prove the following theorem:

if the following are true:

expression state at time 16 = "return"
Class Map at time 16 = [ ]

then Class Map at time 17 = [ ]

Proof:

Given

1	expression state at time 16 = "return"
2	Class Map at time 16 = [ ]

Proof Table

#	Claim	Reason
1	Class Map at time (16 + 1) = Class Map at time 16	if expression state at time 16 = "return", then Class Map at time (16 + 1) = Class Map at time 16 (Return (11))
2	Class Map at time (16 + 1) = [ ]	if Class Map at time (16 + 1) = Class Map at time 16 and Class Map at time 16 = [ ], then Class Map at time (16 + 1) = [ ] (Transitive Property of Equality)
3	16 + 1 = 17	16 + 1 = 17 (Fixed Value Statement)
4	Class Map at time (16 + 1) = Class Map at time 17	if 16 + 1 = 17, then Class Map at time (16 + 1) = Class Map at time 17 (Substitution)
5	Class Map at time 17 = [ ]	if Class Map at time (16 + 1) = Class Map at time 17 and Class Map at time (16 + 1) = [ ], then Class Map at time 17 = [ ] (Transitive Property of Equality Variation 2)
