A(C+D) + BCD + ACD + ABCD = AC + AD + BCD + ACD + ABCD (分配律)
= AC + AD + BCD + ACD + ABC + ABCD - ABC (集合论恒等式)
= AC + AD + ABC + BCD + ACD + ABCD - ABC (合并同类项,即ACD和ABC可以合并)
= AC(1 + B + D) + AD + BCD + ABC(1 + D - 1) (分组和二项式定理)
= AC(1 + B + D) + AD + BCD + ABCD(1 - 1) (因为1+D=1,所以可以化简)
= AC(1 + B + D) +

化简逻辑函数A(C+D)+BCD+ACD+ABCD
A(C+D) + BCD + ACD + ABCD
= AC + AD + BCD + ACD + ABCD (分配律)
= AC + AD + BCD + ACD + ABC + ABCD - ABC (集合论恒等式)
= AC + AD + ABC + BCD + ACD + ABCD - ABC (合并同类项,即ACD和ABC可以合并)
= AC(1 + B + D) + AD + BCD + ABC(1 + D - 1) (分组和二项式定理)
= AC(1 + B + D) + AD + BCD + ABCD(1 - 1) (因为1+D=1,所以可以化简)
= AC(1 + B + D) +
= AC(1 + B + D) + AD + BCD + ABCD(0)
(因为1-1=0,所以可以化简)
= AC(1 + B + D) + AD + BCD
(去零术)
所以化简后的逻辑函数是 AC(1 + B + D) + AD + BCD
