Here's a few hints:

  • the function that rounds numbers is Math.round
  • when you call a function, you follow the name with parentheses
  • inside the parentheses, you put any arguments that you want the function to work with
  • a variable name should not be enclosed in quotes, that turns it into a string
var temperature = 37.5;
alert(Math.round(//Variable name will go here) + ' degrees');

remember Math.round() the M is always capitalized.
