unary operator

In the editor, initialScore represents a user's score in a game. A user managed to beat the current level so first, let's add 1 point to their initial score using the unary plus operator.

var initialScore = 8

operators.swift 
// Enter your code below
var initialScore = 8

Hi there! I received your request for assistance. I wish I knew what you had already tried that's failing so that I could better explain what you've missed. I can, however, point you to 1:27 in this video where Pasan explains how the unary operator is used to increment a value.

Good luck! :sparkles:
