Processing Details
Conductive status when (S1) = (S2)
Non-Conductive status when (S1)  (S2)
Conductive status when (S1) > (S2)
Non-Conductive status when (S1) ≤ (S2)
Conductive status when (S1) < (S2)
Non-Conductive status when (S1) ≥ (S2)
Conductive status when (S1+1, S1) = (S2+1, S2)
Non-Conductive status when (S1+1, S1)  (S2+1, S2)
Conductive status when (S1+1, S1) > (S2+1, S2)
Non-Conductive status when (S1+1, S1) ≤ (S2+1, S2)
Conductive status when (S1+1, S1) < (S2+1, S2)
Non-Conductive status when (S1+1, S1) ≥ (S2+1, S2)
Processing Details
(S1)+(S2) → (D)
(S1)-(S2) → (D)
(S1+1, S1) + (S2+1, S2) → (D+1, D)
(S1+1, S1) - (S2+1, S2) → (D+1, D)
(S1) × (S2) → (D+1,D)
(S1) / (S2) → Quotient (D), Remainder (D+1)
(S1+1, S1) × (S2+1, S2) → (D+3, D+2, D+1, D)
(S1+1, S1) / (S2+1, S2)
→ Quotient (D+1, D), Remainder (D+3, D+2)
(D)+1 → (D)
(D+1, D)+1 → (D+1, D)
(D)-1 → (D)
(D+1, D)-1 → (D+1, D)
