Proof: Write Skip Line Tab 6

Let's prove the following theorem:

if the following are true:
  • the line at time 6 = 7
  • the tab at time 6 = 1
  • statement at line 7, tab 2 = return self.age * 12

then the tab at time 7 = 1

Given
1 the line at time 6 = 7
2 the tab at time 6 = 1
3 statement at line 7, tab 2 = return self.age * 12
Proof Table
# Claim Reason
1 2 > 1 2 > 1
2 the tab at time (6 + 1) = the tab at time 6 if the line at time 6 = 7 and the tab at time 6 = 1 and statement at line 7, tab 2 = return self.age * 12 and 2 > 1, then the tab at time (6 + 1) = the tab at time 6
3 the tab at time (6 + 1) = 1 if the tab at time (6 + 1) = the tab at time 6 and the tab at time 6 = 1, then the tab at time (6 + 1) = 1
4 6 + 1 = 7 6 + 1 = 7
5 the tab at time (6 + 1) = the tab at time 7 if 6 + 1 = 7, then the tab at time (6 + 1) = the tab at time 7
6 the tab at time 7 = 1 if the tab at time (6 + 1) = the tab at time 7 and the tab at time (6 + 1) = 1, then the tab at time 7 = 1
