what is de Morgan’s first law
¬(A v B) = ¬A ^ ¬ B
what is de Morgan’s second law

what are the 8 general rules of boolean algebra
- X ^ 0 = 0
- X ^ 1 = X
- X ^ X = X
- X ^ ¬X = 0
- X v 0 = X
- X v 1 = 1
- X v X = X
- X v ¬X = 1

what are the commutative rules
- X ^ Y = Y ^ X
- X v Y = Y v X
simplify, reorganise or expand X ^ Y = ? and name the rule used
Y ^ X
commutative
simplify, reorganise or expand X v Y = ? and name the rule used
Y v X
commutative
simplify, reorganise or expand ¬(A v B) = ? and name the rule used
¬A ^ ¬ B
de Morgan’s first law
simplify, reorganise or expand ¬(A ^ B) = ?and name the rule used
¬A v ¬ B
de Morgan’s second law
what are the associative rules
- X ^ ( Y ^ Z) = (X ^ Y) ^ Z
- X v (Y v Z) = (X v Y) v Z
simplify, reorganise or expand X ^ ( Y ^ Z) = ? and name the rule used
(X ^ Y) ^ Z
associative
simplify, reorganise or expand X v ( Y v Z) = ? and name the rule used
(X v Y) v Z
associative
what are the distributive rules
- X ^ (Y v Z) = (X ^ Y) v (X ^Z)
- (X v Y) ^ (W v Z) = (X ^ W) v ( X ^ Z) v (Y ^ W) v (Y ^ Z)
