// 创建 factory MathService 用于两数的乘积 provides a method multiply to return multiplication of two numbers
          p 输入一个数字: input type = number ng-model = number / /p
      script src= http://apps.bdimg.com/libs/angular.js/1.4.6/angular.min.js /script
            $provide.provider( MathService , function() {
         mainApp.service( CalcService , function(MathService){
         mainApp.controller( CalcController , function($scope, CalcService, defaultInput) {
            $scope.result = CalcService.square($scope.number);
               $scope.result = CalcService.square($scope.number);
