Hi there! You were doing well up until step 2. Step 2 explicitly asks you to use concatenation to add a new element to the array. Remember, that concatenation uses a plus sign. Take a look:

var arrayOfInts = [1, 2, 3, 4, 5, 6]
arrayOfInts.append(7)
arrayOfInts += [8]

I hope this helps! Good luck on steps 3 and 4 :sparkles:

As I understood it, you need to concatenate two arrays, like this arrayOfInts += [7,8]

Hope this helps
