Jason please give me a hint I really need help thx for your time everyone

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 = 15 % 5
// Task 2 - Enter your code below
let isPerfectMultiple = 3 > 0

let isGreater = "\(someOperation) true"

Hi Rico,

isPerfectMultiple should be using the equality operator (==) not a greater-than operator (>).

As far as the isGreater property, you will want to compare someOperation to anotherOperation.

For instance, if I have the following code

let isLesser = 3<5

then isLesser will contain the boolean value of true because 3 is less than 5.

so if I want to know if an operation is greater than or equal to another operation, I will use the correct operator to find out (>=)

let isGreater = someOperation >= anotherOperation

now isGreater contains either true if someOperation is greater than or equal to another operation or false if it is not greater or equal to.

Reference the solution here if you are still having a hard time

// 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

let isGreater = someOperation >= anotherOperation
