The challenge question is just to show you that you can add together any two numbers using the + operator. In this case, you’re assigning the sum of those two numbers to a variable sum.

Any numbers will work in this case, and you can also use the operator in more complex situations. For example, you could write a function to add numbers together.

const sumOfTwo = (num1, num2) => {
return num1 + num2;
} // Returns the sum of any numbers input as num1 and num2
sumOfTwo(12, 14); // Should return 26
