Hi Berry,

The answer is 3 because 7 does not fit into 3 as you said. Since it does not fit, you are left with everything (i.e. 3).

If you play in the playground in Xcode, you can see this yourself.

let answer1 = 3%2 // remainder = 1.  2 fits into 3 once and you are left with 1
let answer = 3%7 // remainder = 3.  7 does not fit so you are left with everything (3)

I hope that helps,


PS: Thanks to the awesome resources on Team Treehouse, I launched my first app.

Now you can practice writing Swift code directly on your iPhone :-)
