In the solution video, all the conditions are surrounded by parenthesis. Why is this? I had a very similar solution but with no parenthesis.

You may want to take a look at the video for operator precedence. There you’ll find your answer to why he uses them. In this example it’s optional, and you can have your code without the parenthesis.

Thanks for the response. As you suggested I took another look at the operator precedence video. This cleared everything up. Thanks again.
