> There are various issues w.r.t. type checking in math.scala. Most of the custom implementation of checkInputTypes can be replaced with mixin ExpectsInputTypes.
> There are also other minor issues, such as over complicating certain expressions due to the previous lack of implicit type casting among numeric types.
