Proof: Do Class Defs At Unchanged 2

Let's prove the following theorem:

if the following are true:

expression state at time 2 = "begin_expr"
Class Map at time 2 = [ ]

then Class Map at time 3 = [ ]

Proof:

Given

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

Proof Table

#	Claim	Reason
1	Class Map at time (2 + 1) = Class Map at time 2	if expression state at time 2 = "begin_expr", then Class Map at time (2 + 1) = Class Map at time 2 (Insn Count Begin Expression (8))
2	Class Map at time (2 + 1) = [ ]	if Class Map at time (2 + 1) = Class Map at time 2 and Class Map at time 2 = [ ], then Class Map at time (2 + 1) = [ ] (Transitive Property of Equality)
3	2 + 1 = 3	2 + 1 = 3 (Fixed Value Statement)
4	Class Map at time (2 + 1) = Class Map at time 3	if 2 + 1 = 3, then Class Map at time (2 + 1) = Class Map at time 3 (Substitution)
5	Class Map at time 3 = [ ]	if Class Map at time (2 + 1) = Class Map at time 3 and Class Map at time (2 + 1) = [ ], then Class Map at time 3 = [ ] (Transitive Property of Equality Variation 2)
