Question: After installing angular material, the following were added to index.html:

```
<link href="https://fonts.googleapis.com/css?family=Roboto:300,400,500&display=swap" rel="stylesheet">
<link href="https://fonts.googleapis.com/icon?family=Material+Icons" rel="stylesheet">

```

Is there a way to download these css file and reference locally?

Answer: 
You might have lost ')' in:

```
x=int(input('Insert no.')) <- close bracket

```
You need a closing parentheses when defining x. Here is the corrected code:

```
x=int(input('Insert no.'))

```
