I'm confused on how to increment initialScore once if I'm suppose to declare totalScore as a constant.

I thought that I can simply add ++ to the assigned value of initialScore. The challenge keep saying increment the value of initialScore once. I;m not sure what I'm doing wrong.

operators2.swift 
// Enter your code below

var initialScore = 8
let totalScore = ++initialScore
initialScore = ++initialScore


let isWinner = 10 != 10

Okay. You almost got it. The challenge is asking that you create a constant called isWinner, then assign the results of a comparison operation. It seems like in your code, you are assigning the incremented value of initialScore to totalScore (let totalScore = ++initialScore), then re-increment the value of initialScore again. That's where the error is coming from.

I believe you need something like this to solve your problem:

var initialScore = 8

let totalScore = ++initialScore

let isWinner = totalScore != 10
