You can just replace the current Tutorials/Mathematicians folder in your project by that new one :wink:

Your Homework for next week is:

  • Implement theories for commutative magma, commutative semigroup and commutative monoids. Make them modular, i.e. try to include theories wherever possible without writing down anything twice.
    -Implement views from commutative monoids to NaturalAddition and NaturalMultiplication. Again: try to be as modular as possible.
