Proof: Do Tab At Unchanged 32

Let's prove the following theorem:

if the following are true:
  • expression state at time 32 = "iterate_args"
  • the tab at time 32 = 0

then the tab at time 33 = 0

Given
1 expression state at time 32 = "iterate_args"
2 the tab at time 32 = 0
Proof Table
# Claim Reason
1 the tab at time (32 + 1) = the tab at time 32 if expression state at time 32 = "iterate_args", then the tab at time (32 + 1) = the tab at time 32
2 the tab at time (32 + 1) = 0 if the tab at time (32 + 1) = the tab at time 32 and the tab at time 32 = 0, then the tab at time (32 + 1) = 0
3 32 + 1 = 33 32 + 1 = 33
4 the tab at time (32 + 1) = the tab at time 33 if 32 + 1 = 33, then the tab at time (32 + 1) = the tab at time 33
5 the tab at time 33 = 0 if the tab at time (32 + 1) = the tab at time 33 and the tab at time (32 + 1) = 0, then the tab at time 33 = 0
