Hi there! It looks like you're doing pretty well and understanding interpolation, but your string doesn't match what they want. Currently, the constant output would hold this string: "10 * 20 is product". But they want your string to look like this: "The product of 10 times 20 is 200". You also are forgetting to interpolate \(product) like you did with your first two variables. Once you fix the formatting of the string, you should pass.

Hope this helps! :sparkles:
