var app = angular.module('app', []);
                app.factory('MathService', function(){
                    return {
                        multiply : function(a, b){
                            return a*b;
                        }
                    }
                });

                app.factory('CalculateResult', ['MathService', function(MathService){
                        return {
                            square : function(a){
                                return MathService.multiply(a,a);
                            },

                            cube : function(a){
                                return MathService.multiply(a, MathService.multiply(a,a));
                            }
                        }
                }]);

                app.controller('CalculatorController', ['CalculateResult', '$scope', function(CalculateResult, $scope){

                    $scope.doSquare = function(){
                        $scope.answer = CalculateResult.square($scope.number);
                    };

                    $scope.doCube = function(){
                        $scope.answer = CalculateResult.cube($scope.number);
                    }

                }]);

这是答案感谢支持
