Hi Paulina,

Brian's answer is close. You need to wrap the mathy part in parentheses. For the challenge, you'll actually need both versions of the print statements Brian suggested. However, you need to use println so it prints each time on a new line, and you need to escape the parentheses. You also should be multiplying by 7, not 2, per the challenge.

for_loops.swift 
for item in 1...10 {
    println("\(item) * 7 = \(item*7)")
}

youre just mis-using the parentheses. like this i believe----- Println("(item)*2") ----- to get "4*2" or use ------ ---------Println("(item*2)") to get "8"

hope it helped
