Proof: Do Tab At Unchanged 38

Let's prove the following theorem:

if the following are true:
  • expression state at time 38 = "iterate_args"
  • the tab at time 38 = 0

then the tab at time 39 = 0

Given
1 expression state at time 38 = "iterate_args"
2 the tab at time 38 = 0
Proof Table
# Claim Reason
1 the tab at time (38 + 1) = the tab at time 38 if expression state at time 38 = "iterate_args", then the tab at time (38 + 1) = the tab at time 38
2 the tab at time (38 + 1) = 0 if the tab at time (38 + 1) = the tab at time 38 and the tab at time 38 = 0, then the tab at time (38 + 1) = 0
3 38 + 1 = 39 38 + 1 = 39
4 the tab at time (38 + 1) = the tab at time 39 if 38 + 1 = 39, then the tab at time (38 + 1) = the tab at time 39
5 the tab at time 39 = 0 if the tab at time (38 + 1) = the tab at time 39 and the tab at time (38 + 1) = 0, then the tab at time 39 = 0
