Unable to use the parenthesis in an expression

I am having a silly issue. How do I use the () in my expressions for math calculations? Example: (x / y) * z. I want to find the percentage of something, but unable to complete it without having to create a backend api workflow and additional fields to my app data, which I think is unnecessary. Thanks!

You can use the paranthesis feature in Bubble (just enable that in the Settings → Version of your Bubble app)
