Actually don't understand what we are expected to do as it is not clear

Are we supposed to be substituting the results of the constants someOperation and anotherOperation into the formula let result = value % divisor?

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
let isPerfectMultiple

// Task 2 - Enter your code below

HI Alison,

Your step 1 is correct.

For step 2 you need to evaluate whether result is equal to 0. This will yield a Bool: true or false. The isPerfectMultiple constant will hold that boolean.

Hope that helps

Cheers

Hi Alison,

Your first step is right, in this step the result of the reminder operator (%) is 0. For step 2 you have to compare if the result of you first step is 0.

Could be like this...... let isPerfectMultiple = "result" == 0 and the result of this operation is true.
