Hi James. A boolean is a variable that takes only two values (binary): true or false. The challenge wants us to create a constant named "isGreater" and assign the boolean value from the comparison "someOperation is greater or equal to anotherOperation." We do this like so:

let isGreater = someOperation >= anotherOperation

Hope this helped. :D
