For if I is maximal , then R / I is a commutative ring with

For if I is maximal , then R / I is a commutative ring with

**unit**which has no proper ideals ; by what we showed earlier R / I is a field .Page 41

Further , from the above we see that if M is a maximal ideal in a Boolean ring R with

Further , from the above we see that if M is a maximal ideal in a Boolean ring R with

**unit**, then R / M is isomorphic with the field .Page 458
