Proof: Do Variables At Unchanged 7

Let's prove the following theorem:

if the following are true:
  • expression state at time 7 = "iterate_args"
  • Variables Map at time 7 = [ ]

then Variables Map at time 8 = [ ]

Proof:

Given
1 expression state at time 7 = "iterate_args"
2 Variables Map at time 7 = [ ]
Proof Table
# Claim Reason
1 Variables Map at time (7 + 1) = Variables Map at time 7 if expression state at time 7 = "iterate_args", then Variables Map at time (7 + 1) = Variables Map at time 7
2 Variables Map at time (7 + 1) = [ ] if Variables Map at time (7 + 1) = Variables Map at time 7 and Variables Map at time 7 = [ ], then Variables Map at time (7 + 1) = [ ]
3 7 + 1 = 8 7 + 1 = 8
4 Variables Map at time (7 + 1) = Variables Map at time 8 if 7 + 1 = 8, then Variables Map at time (7 + 1) = Variables Map at time 8
5 Variables Map at time 8 = [ ] if Variables Map at time (7 + 1) = Variables Map at time 8 and Variables Map at time (7 + 1) = [ ], then Variables Map at time 8 = [ ]
