CD+BCD+A'BC'D'+ABC'D'+A'B'CD'+AB'CD'
= CD + B'CD + BC'D' + B'CD'
(BCD 變 B'CD 是因為已經有 CD 的關係)
= CD + B'C + BC'D'
由卡諾圖
| CD CD' C'D' C'D
--------------------------------
AB | 1 0 1 0
AB' | 1 1 0 0
A'B' | 1 1 0 0
A'B | 1 0 1 0
=> CD + B'C + BC'D'
如果有問題, 請來函討論. 不然, 我可能會錯失你再補充的疑點.

CD+BCD+A'BC'D'+ABC'D'+A'B'CD'+AB'CD' =
(BCD + B'CD) + BCD + (A'BC'D'+ABC'D') + (A'B'CD'+AB'CD') =
BCD + B'CD+ BC'D' + B'CD' =
(BCD + B'CD) + B'CD + BC'D' + B'CD' =
CD + (B'CD + B'CD') + BC'D' =
CD + B'C + BC'D'
