Hey MATTHEW MARRERO,

The challenge gives you two constants with integer values, these are value and divisor.

Task 1: It wants you to use these two values to calculate the remainder of the value divided by the divisor, and then assign the result to the constant result. We can do this calculation using the remainder operator, %.

Task 2: This task wants you to compare the result constant you created in the previous task to 0. You can do this using the equality operator, ==. If the value for result is equal to 0, the comparison will return true. If the value for result is not 0, the comparison will return false. The result of this comparison is stored in the constant isPerfectMultiple.

Since 200 divided by 5 has no remainder, it is a perfect multiple and the result will be 0. This means the comparison of result to 0 will evaluate to true, and therefore isPerfectMultiple will be assigned the value of true.

// 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

Good Luck!
