I am completely lost on the part 2 to this question,

How would I show Part 2 ? I am so lost thank you for your help in advance! :)

operators.swift 
// Enter your code below
let value = 200
let divisor = 5
let result = value/divisor
let someOperation = 20 + 400 % 10 / 2 - 15
let anotherOperation = 52 * 27 % 200 / 2 + 5

Part 1 of the task asks you to find the remainder when you divide value by divisor, not the quotient. Because of this, you need to use the mod operator when calculating result, not the division operator.

let result = value/divisor // USE %, NOT /

After this, Part 2 asks you to assign to isPerfectMultiple a bool that is true when result is equal to 0, and false when result is not equal to 0. The expression "result == 0" evaluates to true when result is 0, and false when result isn't 0; thus, this is the expression you need to assign to isPerfectMultiple:

let isPerfectMultiple = result == 0

I hope this helps!
