I treed the rest of the expressions in @Eternity 's post. The file with the expressions is called Practice Trees.pdf
Tree #1:
Looks like we got the same answer
Tree #2:
or(or(or(and(and(x,y),~z), and(and (~x,y), z)),and(and(x,~y),z)), or(or(and(and(x,~y), ~z)),and(and (~x,y), ~z)),and(and (~x,~y), z)):
We got different answers and I think it’s cuz an end parenthesis is in the wrong place. I got the same answer after moving them:
The answer:
Tree #3:
((x∧~y∧~z)∨(~x∧y∧~z)∨(~x∧~y∧z))∨(x∧y∧z)
Tree #4:
Same answer
I had trouble making the trees at first but after thinking of a method to do them it got easier. It just took some practice to learn and it was good.
