Friends can any one please tell me all the boolean algebra calculations needed to solve logic gates problems having many combination

just post the formulas raates assured for correct and complete ans

RyuAmakusa

(A+B)'=B'A'
(AB)'=A'+B'
if you take compliment even no. of times the function remains same

I did not understand exatly what type of formula may be if you give some question it would give a better idea

avi_1214545

if any odr doubt or ques...plzz ask...m in comp sci too...

(A'+B')'=A.B

(A'.B')'=A+B

THESE TWO ARE DE MORGANS LAWS

(A+B).A'=A'.B

(A+B)=A.B

THESE ARE KNOWN AS ABSORPTION LAWS

(A')'=A

A.A=A

ETC

THERE ARE MANY!!!!
