iOS Swift Basics Swift Operators Working With Operators

I feel like I've done everything right, I'm not sure where to go from here

I'm stuck , please help

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
result == 0
 let isPerfectMultiple = false

someOperation == anotherOperation

let isGreater = false

Okay, so you've got a few things wrong here.

First in task one, it says to use the remainder operator to compute the remainder of the value and the divisor. You used the division operator. % is the remainder operator. so task one should look like this.

// Enter your code below

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

Then, for task number two, you're supposed to compare what's in result with 0 to see if they are equal. If so then you set the isPerfectMultiple constant to true, otherwise, set it to false. So what you want to do in this situation where you comparing two things and deciding what to do afterwards is to use an if statement. You'll also need to go ahead and declare the isPerfectMultiple constant, but not assign it anything yet, because you declare inside the if statement, it will only exist inside that if statement, and you won't be able to use it elsewhere. So the second step should look like this.

// Task 2 - Enter your code below
let isPerfectMultiple: Bool
if result == 0 {
    isPerfectMultiple = true
 } else {
    isPerfectMultiple = false
  }

Does all that make sense?
