sum the total in an ng-repeat

Question

I am a beginner in German and I have the following problem and I don’t know how to solve it!

I have a table and I need to calculate the total waste adding up all prices. Inside ng-repeat has a column where it displays all the values of residuals, but I don’t know the syntax to read these column items and add.

Someone could help me?

$scope.somarValores = function(){
	    $scope.total = $scope.pedidos.residuoModel.preco + $scope.pedidos.residuoModel.preco
	}

                        <tr ng-repeat="pedidosTabela in pedidos | filter: pesquisaPed"ng-click="selecionaPedido(pedidosTabela)">
                          <td>{{pedidosTabela.id}}</td>   
                          <td>{{pedidosTabela.data}}</td>
                          <td>{{pedidosTabela.fornecedorModel.nome}}</td>
                          <td>{{pedidosTabela.categoriaModel.nome}}</td>
                          <td>{{pedidosTabela.residuoModel.nome}}</td>                          
                          <td>{{pedidosTabela.residuoModel.status}}</td>
                          <td>{{pedidosTabela.residuoModel.preco | currency}}</td>
                          <td>{{pedidosTabela.residuoModel.peso}}</td>
                          <td>{{pedidosTabela.residuoModel.situac}}</td>

You’ll need to do a breakdown to calculate everything.

$scope.somarValores = function(){
    $scope.total = 0;
    for(var i = 0; i < $scope.pedidos.length; i++) {
       $scope.total += $scope.pedidos[i].residuoModel.preco
    }
}
