(A AND B)
OR
(C AND D)
= Q
6
(A AND B) OR (C AND D) = Q
7
(A AND B) OR (C AND D) = Q
8
(A ⋅ B) + (C ⋅ D) = Q
9
A ⋅ B + C ⋅ D = Q
10
A ⋅ B + C ⋅ D = Q
A | B | C | D | Q |
|---|---|---|---|---|
0 | 0 | 0 | 0 | 0 |
1 | 0 | 0 | 0 | 0 |
1 | 1 | 0 | 0 | 1 |

(A OR B) AND (C OR D) = Q
13
(A OR B) AND (C OR D) = Q
14
(A OR B) AND (C OR D) = Q
(A+B)⋅(C+D) = Q

16
A OR B AND NOT C = Q
17
A OR B AND NOT C = Q
18
(A + B) ⋅ C = Q
_
​A OR B AND NOT C = Q
19
(A . B)+ C = Y
20
(A . B)+ C = Y
NOT (A AND B OR C) = Y
21
(A . B)+C = Y
NOT (A AND B OR C) = Y
