| Identity Name | AND Form | OR Form |
|---|---|---|
| Identity Law | 1x = x | 0 + x = x |
| Null (or Dominance) Law | 0x = 0 | 1 + x = 1 |
| Idempotent Law | xx = x | x + x = x |
| Inverse Law | xx’ = 0 | x + x’ = 1 |
| Commutative Law | xy = yx | x + y = y + x |
| Associative Law | (xy)z = x(yz) | (x + y) + z = x + (y + z) |
| Distributive Law | x + (yz) = (x + y)(x + z) | x(y + z) = xy + xz |
| Absorption Law | x(x + y) = x | x + xy = x |
| DeMorgan’s Law | (xy)’ = x’ + y’ | (x + y)’ = x’y’ |
| Double Complement Law | x” = x | x” = x |
