You're very close! You need to slightly change your print statement.

for number in 1...10 {
  println("\(number) * 7 = \(number * 7)") 
}

No problem :) The syntax is slightly weird to be honest. If you have any other questions or need some clarification, feel free to ask!

In general, a \ means to do something adnormal with the character that is coming next. For instance, in Java, if you do print("Have a great day!\n"); the \n means to add a new line.

In the case of Swift, \( means to read until the ) and pre-process the information before printing it.

Does that make sense?
