// 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

//Create ivar Bool type:
let isPerfectMultiple:Bool

//Compare types with conditional statement:
if result == 0{
isPerfectMultiple = true
}else{
isPerfectMultiple = false

Hi Lahiru!

Let's do a quick code review:

task1.swift
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

// [REVIEW]----- Great! -
let result = value % divisor

// [REVIEW]----- Well done, that will work! 
let isPerfectMultiple = value % divisor == 0

// Don't forget that you already have a value stored in the "result" constant, 
// so why not make our code shorter and easier to read and write something like this:

let isPerfectMultiple = result == 0
task2.swift
// Challenge says: "Use the **greater than** or **equal to** operator and 
// assign the Boolean result of the comparison to a constant named isGreater."

// [REVIEW]-----  There's no need to explicitly stating your type for this challenge. 
// Also you wrote the **less than** or **equal to**
let isGreater : Bool = (someOperation <= anotherOperation) 

// The operator should be **greater than** and can be easily written like so
let isGreater = someOperator >= anotherOperator

Hope this helps! ✊
