360 PointsWhat are the 'someOperation' etc, expressions for in respect to the question. What is the aim of the question?
I do not know what I am doing wrong here, even testing it in Xcode.
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 var result = value%divisor result == 0 let isPerfectMultiple = result isPerfectMultiple == result
// 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
var result = value%divisor
result == 0
let isPerfectMultiple = result
isPerfectMultiple == result
// Task 2 - Enter your code below

13,515 PointsFor starters, "result" is supposed to be a constant, not a variable. Then to check whether 200 / 5 results in a perfect multiple (0), we first create the result constant and assign it to the remainder of 200 / 5 (which is 0), using the remainder operator. Finding the boolean (true or false) value of whether or not the value of "result" (200 / 5) is 0 can be done in one line let isPerfectMultiple = result == 0
// 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
