a) False || ((True && False) || True)

b) ((2/3) / 4 ) == (4/3) /2

c) ((7 - (5/4)) > 6) || ((2^5) - 1 == 31)

d) 2 < 3 < 4 is not well-formed beacuse it would compare a Bool with a number

e) (2 < 3) && (3 < 4)

f) 2 && 3 < 4 is not well formed because it would apply a boolean operator to a number
