Swift Basic 2.0 Comparison Operator Quiz

I'm having difficulty with this current quiz i'm in. Mainly for the second challenge task which is:

"Great job with the first task! In this task, we have two math operations. Without computing the values of those operations, we'd like to know if the first operation, someOperation is greater than, equal to or less than anotherOperation.

Use the greater than or equal to operator and assign the Boolean result of the comparison to a constant named isGreater."

Can anyone help me where I'm making the mistake? I must not understand the question.

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 = result == 0
// Task 2 - Enter your code below
someOperation > anotherOperation
someOperation < anotherOperation
someOperation = anotherOperation
let isGreater = someOperation < anotherOperation; false

This question is similar to part 2 of the first task.

The first task asked you to see if result == 0 and assign the corresponding Bool to the constant isPerfectMultiple. You performed this task by writing the following code:

let isPerfectMultiple = result == 0

This task is asking you to see if someOperation > anotherOperation and assign the corresponding Bool to the constant named isGreater. The code defining isGreater should mirror the code for isPerfectMultiple in structure.

I hope this helps!

Hi Anjali,

Thanks for helping out! I've got it figured out haha!

I'm afraid this wasn't enough of a hint for me. Would you be willing to be more forthcoming with some information?

This is still unclear to me.

It's alright. I'll try to be more clear.

For task 2, you're suppose to create a constant called isGreater. This constant should be true if someOperation > anotherOperation, and false otherwise.

The expression "someOperation > anotherOperation" evaluates to true if someOperation is greater than anotherOperation, and evaluates to false otherwise.

Thus, you need to assign the constant "isGreater" to the expression "someOperation > anotherOperation":

let isGreater = someOperation > anotherOperation

I hope this helps!
