I have trouble on the task 2 I think

I need to find out what is wrong(:

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 = result

Under Task 1 you create a constant, result, and assign a value to get it, but then, under task 2 you assign it a value (0) to the constant. A constant's value is, well constant. You can't change it by assigning a value to it (even if it is the same value that it came out to under Task 1.

Hey there,

you almost got it right, good job! However you shouldn't set result to 0 manually but you should compare it to 0 with the is equal operator. Then you should assign the result of the comparison 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! :)
