Not sure why answer is incorrect.

I believe I am using the != correctly.

operators2.swift 
// Enter your code below

var initialScore = 8
let totalScore = ++initialScore
let isWinner =true
let isWinner !=10

Hey Kristine,

the problem here is that you're manually assigning the value true to isWinner and then you're comparing if this value (true) is not equal to 10. This doesn't really make sense in this case and you're not using the totalScore constant at all which means that the score doesn't influence isWinner . To change that you have to assign the value of the comparison between 10 and totalScore with the inequality operator to isWinner .

Like so:

// Enter your code below

var initialScore = 8
let totalScore = ++initialScore
let isWinner = totalScore != 10

I hope that makes sense and helps, if you have further questions feel free to ask. Good luck! :)
