        dumb + \.string - "Hello!" + \.double - 3.14 + \.array - [1, 43, 6, true]

        ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~

#### Solution

**Make sure to use parentheses!**

```swift

var dumb = DumbStruct()

        

(((dumb + \.string - "Hello!")

     + \.double - 3.14)

     + \.array - [1, 43, 6, true])

XCTAssertEqual(dumb.string, "Hello, World!")

```
