Tell us what’s happening:

Your code so far


function mixedNumbers(arr) {
  // change code below this line
arr.unshift("I");
arr.unshift(2);
arr.unshift("'three'");
arr.push(7);
arr.push("'VIII'");
arr.push(9);
  // change code above this line
  return arr;
}

// do not change code below this line
console.log(mixedNumbers(['IV', 5, 'six']));

It’s saying add the string 'three', for example, not the string "'three'"
