// 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

var someOperation >= var anotherOperation

I guess you're talking about task 2 here. What you did is, you used the var keyword again in your comparison. Fact is: The var or let keyword is only needed when you first create a variable, like they did with

let value = 200
let divisor = 5

in the given example. Later on, in task 1, you used these two constants by using their name without the let keyword:

let result = value % divisor

This is what you should do now, use the constants someOperation and anotherOperation without any keyword in front of them - you already declared these two.

I admit, I struggled with that question a bit, too. I found the question itself confusing. What they want you to do:

Create a constant named isGreater. The value you assign to it is the result of the comparison if the result of someOperation is greater than the result of anotherOperation. Which would be:

let isGreater = someOperation >= anotherOperation
