define xor with a truth table.

nope not a homework
i want to make a binary adder cuircuit i dont have an xor gate only and, or & not.

xor = not(a).b + a.not(b)

I also thought this is a homework problem. You can easily get this into and/or gates. If there are more than 2 inputs, you should be using k-maps. Once, you have in and/or gates, it is simple to convert it into nand (using Sum of products form) or nors (using products of sums or simply messing with bool algebra...)
