  1. So, so far, we've seen two different types of domain restrictions. Some of them
  2. are motivated by common sense, problem solving and real world quantities. So for
  3. example as we saw earlier, Athena needs to design Grant's fun room so that the
  4. dimensions are greater than zero. The other type is domain restrictions that are
  5. motivated by math. So restrictions that we need to impose in order to get only
  6. real or properly defined solutions. So an example of this would be avoiding
  7. taking square roots of negative numbers.
