$plus: (FirstValue: Int, SecondValue: Int)Int

scala> +(2,5)

<console>:24: error: value unary_+ is not a member of (Int, Int)

All prefix operators' symbols are predefined: +, -, ~, !. The Scala parser treats these symbols at the beginning of expressions always as unary operators regardless of the real presence of corresponding methods "unary_x". 

This issue is not yet resolved. But there is a  workaround for this. Refer the below screenshot for the same,image

Hope this helps!
