=Problem #1: Boolean Logic=
 +
 +
The three equations below represent three different logic expressions using '''and''', '''or''' and '''not''' gates of three boolean variables A, B, and C.  A boolean variable can take only one of two possible values: True or False.
 +
 +
Which of the two expressions are identical, meaning that for any combination of A, B, and C, they are both True or both False.
 +
 +
 +
* Expression 1:    (A and (not B) ) or ( B and (not A))
 +
 +
* Expression 2:  (A and (not B)) and ( B and ( not A ))
 +
 +
* Expression 3:  (A or B ) and ( not ((A and B ))
 +
 +
 +
* In your answer explain how you figure out which expression is different from the other two.
 +
* Remember that you have a nice circuit simulator available to you to check circuits (See [[CSC103_Lab_1_2011 | Lab #1])
