iOS Swift Basics Swift Operators Working With Operators

Unsure of what the isPerfectMultiple part of this question

Just need to know what i have done wrong. Thanks

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 = 200%5
// Task 2 - Enter your code below
let isPerfectMultiple = 40
let isPerfectMultiple; 40==result

Hi James,

You want to compare result to zero using double equals. Assign that expression into isPerfectMultiple.

The number 40 has crept into your thinking. That's the result of dividing 200 by 5. That's not what the % operator does. The mod operator provides the remainder of the division. So, for 200 % 5 the result is zero. 201 % 5 would evaluate to 1.

The right hand part of the required expression here is a comparison of result with 0. That looks like result == 0. The left side of the code defines a constant called isPerfectMultiple. Join the two with the assignment operator, a single equals.

All that looks like:

let isPerfectMultiple = result == 0

I hope that helps,

Steve.

Thanks Steve, was stuck for a while :D

No problem! :+1:
