Proof: Byte 1 Stays the Same 8

Let's prove the following theorem:

if the following are true:
  • instruction #14 is load dst=3 addr=1 imm=1
  • the PC at time 8 = 14
  • value of cell 1 at time 8 = 126

then value of cell 1 at time 9 = 126

Given
1 instruction #14 is load dst=3 addr=1 imm=1
2 the PC at time 8 = 14
3 value of cell 1 at time 8 = 126
Proof Table
# Claim Reason
1 not (1 = 3) not (1 = 3)
2 value of cell 1 at time (8 + 1) = value of cell 1 at time 8 if instruction #14 is load dst=3 addr=1 imm=1 and the PC at time 8 = 14 and not (1 = 3), then value of cell 1 at time (8 + 1) = value of cell 1 at time 8
3 8 + 1 = 9 8 + 1 = 9
4 value of cell 1 at time (8 + 1) = value of cell 1 at time 9 if 8 + 1 = 9, then value of cell 1 at time (8 + 1) = value of cell 1 at time 9
5 value of cell 1 at time 9 = value of cell 1 at time 8 if value of cell 1 at time (8 + 1) = value of cell 1 at time 9 and value of cell 1 at time (8 + 1) = value of cell 1 at time 8, then value of cell 1 at time 9 = value of cell 1 at time 8
6 value of cell 1 at time 9 = 126 if value of cell 1 at time 9 = value of cell 1 at time 8 and value of cell 1 at time 8 = 126, then value of cell 1 at time 9 = 126
