Stuck on a challenge Comparison Operators task 2

I understand the question but don't understand on how to get a result from a Comparison Operator can someone please explain to me what i'm not understanding?

operators.swift
// Enter your code below
let value = 200
let divisor = 5

let someOperation = 20 + 400 % 10 / 2 - 15
let anotherOperation = 52 * 27 % 200 / 2 + 5

// Task 1 - Enter your code below
let result = value % divisor
// Task 2 - Enter your code below
let isPerfectMultiple = 0
result == isPerfectMultiple

Hi Mustafa,

The comparison operator will return a boolean. For example:

compare.swift
let threeIsLargerThanTen = 3 > 10 // false
let threeIsSmallerThanTen = 3 < 10 // true
let twoPlusTwoEqualsFour = (2 + 2) == 4 // true

So, we want the constant isPerfectMultiple to be true if result is equal to 0. We can do this easily:

checkPerfectMultiple.swift
// Task 1 - Enter your code below
let result = value % divisor

// Task 2 - Enter your code below
let isPerfectMultiple = result == 0

Let me know if this makes sense. As always, it's more important that you understand the why than just getting the challenge right.

Happy coding! :thumbsup:
