Answers to Quizz

I am having difficulty with this quiz. May be I am not understanding the question. Can someone help me please? Thanks!

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
result == 0
let isPerfectMultiple = 0
isPerfectMultiple == result

// Task 2 - Enter your code below

Hey Ibrahim,

you were on the right track but note that when you're comparing using the "is equal" operator you're not saving the resulting value in a variable/constant. So for example if result == 0 evaluates to true this won't be saved in a constant or a variable. And that comparison between result and 0 you already made is basically the solution to the second task, all you have to do is save it to the isPerfectMultiple constant like so:

// 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 = result == 0

I hope that helps! :)
