Hi Alshami,

Do not repeat the var keyword

I'm only going to repeat the lines that need correcting

Wrong

var arrayOfInts.append(7)
var arrayOfInts = var arrayOfInts + [ 8 ]

Revised

arrayOfInts.append(7)
arrayOfInts = arrayOfInts + [ 8 ]

You only need to declare the variable arrayOfInts once in the first line
