• 3 + 1 = 4
• 128 - 1 = 127

• if the following are true:

  • subtract immediate instruction with dst: dst src: src and immediate: imm at i
  • the PC at time t = i

  then value of cell dst at time (t + 1) = (value of cell src at time t) - imm

• if 3 + 1 = 4, then value of cell 1 at time (3 + 1) = value of cell 1 at time 4

• if the following are true:

  • a = b
  • a = c

  then b = c

• if a = b, then a - c = b - c

• if the following are true:

  • a = b
  • b = c

  then a = c

• if the following are true:

  • a = b
  • b = c

  then a = c
