a*b=2^(2a-b)

3*2=2^(2 x 3-2)

3*2=2^(6-2)

3*2=2^(4)

3*2=16

-------------------------------------------------------

a*b=2^(2a-b)

5*3=2^(2 x 5-3)

5*3=2^(10-3)

5*3=2^(7)

5*3=128

-------------------------------------------------------

(3*2)-(5*3) = (16)-(128)

(3*2)-(5*3) = 16-128

(3*2)-(5*3) = -112
