Proof: Do Line At Unchanged 44

Let's prove the following theorem:

if the following are true:
  • expression state at time 44 = "iterate_args"
  • the line at time 44 = 5

then the line at time 45 = 5

Given
1 expression state at time 44 = "iterate_args"
2 the line at time 44 = 5
Proof Table
# Claim Reason
1 the line at time (44 + 1) = the line at time 44 if expression state at time 44 = "iterate_args", then the line at time (44 + 1) = the line at time 44
2 the line at time (44 + 1) = 5 if the line at time (44 + 1) = the line at time 44 and the line at time 44 = 5, then the line at time (44 + 1) = 5
3 44 + 1 = 45 44 + 1 = 45
4 the line at time (44 + 1) = the line at time 45 if 44 + 1 = 45, then the line at time (44 + 1) = the line at time 45
5 the line at time 45 = 5 if the line at time (44 + 1) = the line at time 45 and the line at time (44 + 1) = 5, then the line at time 45 = 5
