How do you write the Boolean expression for XOR gate?

For 2-input EX-OR gate, if one input is A, the other input is B, and the output is Y. Then the Boolean expression for EX-OR (XOR) function (gate) is Y=A⊕B The output Y is true if either input A or if input B is true, but not both.

Y= ( (A and NOT B) or (NOT A and B) ) ;
