Why does the answer from my prompt get compared with a number when it's not supposed to, as the video said?

var randomNumber = Math.floor(Math.random() * 6) + 1;
var guess1 = prompt("Guesser 1    I am guessing a number from 1 through 6. What is my number?");
var guess2 = prompt("Guesser 2    I am guessing the same number from 1 through 6. What is my number?");
if (Math.abs(randomNumber - guess1) < Math.abs(randomNumber - guess2)) {
  document.write("Guesser 1 wins! The number was " + randomNumber + ".");
} else if (Math.abs(randomNumber - guess1) > Math.abs(randomNumber - guess2)) {
  document.write("Guesser 2 wins! The number was " + randomNumber + ".");
}
else if (Math.abs(randomNumber - guess1) === Math.abs(randomNumber - guess2)) {
  document.write("Tie! The number was " + randomNumber + ".");
}

i am not completely sure what you are asking. However you have to change the prompt input from a string to a number. Remember that user input initially is a string that needs to be changed to a number to do math on it. You can use the 

parseInt()

method for whole numbers and 

parseFloat()
``` for decimal numbers. hope that helps and happy coding
