Struggling with the print statement for this challenge. The "\" seems to mess up the code

I keep getting the error "Invalid escape sequence in literal". The same message appeared when I tried typing the following word-for-word from Pasan's video:

for number in 1...10 { print("(number) times 5 is equal to \ (number * 5)") }

loops.swift 
// Enter your code below
var results: [Int] = []

So in the first challenge task they wanted you to make the for loop. You did that well, except they want you to name the loop iterator multipler not number.

For the second task they want you to get that multiplier and muliply it by 6 then append that to your empty array.

Your code would then look like this.

var results: [Int] = []

for multiplier in 1...10 { 
    results.append(multiplier * 6)
}

I hope this helps. :)
