### Tell us what’s happening:

De esta manera he podido darle una solucion al ejercicio:

function multiplyAll(arr) {  
var product = 1;  
// Cambia solo el código debajo de esta línea  
var arreglo = arr;

for (var i = 0; i \< arr.length; i++) {  
for (var j = 0; j \< arr[i].length; j++) {  
product \*= arr[i][j];  
}  
}  
// Cambia solo el código encima de esta línea  
return product;  
}  
var product = multiplyAll([[5,1], [0.2, 4, 0.5], [3, 9]]);  
console.log(product);

### Your code so far

```javascript
function multiplyAll(arr) {
  var product = 1;
  // Cambia solo el código debajo de esta línea
  var arreglo = arr;

for (var i = 0; i < arr.length; i++) {
  for (var j = 0; j < arr[i].length; j++) {
    product *= arr[i][j];
 }
   }
    // Cambia solo el código encima de esta línea
  return product;
 }

var product = multiplyAll([[5,1], [0.2, 4, 0.5], [3, 9]]);
console.log(product);

```
