Proof: Write Stmt Class Defs At Unchanged 35

Let's prove the following theorem:

if the following are true:
  • the line at time 35 = 3
  • the tab at time 35 = 1
  • statement at line 3, tab 1 = a = __add__(a, 1)
  • Class Map at time 35 = [ ]

then Class Map at time 36 = [ ]

Given
1 the line at time 35 = 3
2 the tab at time 35 = 1
3 statement at line 3, tab 1 = a = __add__(a, 1)
4 Class Map at time 35 = [ ]
Proof Table
# Claim Reason
1 Class Map at time (35 + 1) = Class Map at time 35 if the line at time 35 = 3 and the tab at time 35 = 1 and statement at line 3, tab 1 = a = __add__(a, 1), then Class Map at time (35 + 1) = Class Map at time 35
2 Class Map at time (35 + 1) = [ ] if Class Map at time (35 + 1) = Class Map at time 35 and Class Map at time 35 = [ ], then Class Map at time (35 + 1) = [ ]
3 35 + 1 = 36 35 + 1 = 36
4 Class Map at time (35 + 1) = Class Map at time 36 if 35 + 1 = 36, then Class Map at time (35 + 1) = Class Map at time 36
5 Class Map at time 36 = [ ] if Class Map at time (35 + 1) = Class Map at time 36 and Class Map at time (35 + 1) = [ ], then Class Map at time 36 = [ ]
