what is wrong with my answer

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 = true

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 = true

Hey Nguyen,

The second part of the challenge wants you to assign the comparison value (a boolean) to the variable isPerfectMultiple, but you are hard coding in the value.

First off, you can't alter the result variable as this is being set by the arithmetic done in Task 1. Second, you are (and can't) hard code a boolean value for isPerfectMultiple. This needs to be set as a result of the calculation.

So, delete the two lines you have for Task 2, and add just the one line that will assign the result of the comparison to the variable.

let isPerfectMultiple = (result == 0)

The above will assign the resulting boolean of (result == 0) to the variable.

Hope this makes sense. :dizzy:
