-##Summary
+## Summary
 An alternative approach to controllers assumes that the function should be assigned to the controller, not to the $scope.
 Create `SumCtrl` and `SubCtrl` providing the basic math sum (`addition`)and subtract (`subtraction`) functions according to the requirements.
 
-##Goals
+## Goals
 * `Calc.js` should contain `SumCtrl` and `SubCtrl` controllers
 * `SumCtrl` should have the `addition` function assigned to itself
 * `addition` should consume two arguments and assign the result to `sum` variable
