Hey James,

I feel you may be misinterpreting the instructions.
There are two parts to the second task, and each part is individual in itself. The first part wants you to use append() to add a value and the second part wants you to use concatenation to add another value, so the answer will be two lines of code like so:

arrayOfInts += [8]

It may be a good idea to have a quick review of Adding Items to Arrays before moving on.

Keep Coding! :) :dizzy:

thank you

i typed everything in like you said and it worked, but i dont understand why the bottom is 8 lol?

The 8 is just the value I chose to add to the array. If I knew how to count, I would have used 7 Lol :see_no_evil:.
So, it could have be anything really...
