I want to add a new number to an exist array and I should use concatenate method. My code looks fine, but it cannot pass the quiz. Would you help me to figure out this problem? Thank you so much!

// Enter your code below

var arrayOfInts : [Int] = [1,2,3,4,5,6]

arrayOfInts.append(8)

arraryOfInts = arraryOfInts + [9]

Hey Xiufen Xu,

You just misspelled arrayOfInts. Simple fix.

// Enter your code below

var arrayOfInts: [Int] = [1, 2, 3, 4, 5, 6]
arrayOfInts.append(8)
arrayOfInts = arrayOfInts + [9]

Good Luck
