I tried alert () and Math.round() methods .

var temperature = 37.5;
'alert'() (37.5);

You've gone a bit off track, maybe a few hints will help:

  • function names should never be enclosed in quotes
  • calling a function involves putting one pair of parentheses after the function name
  • any arguments to the function go between the parentheses
  • arguments can include calling other functions
  • you will still need to use Math.round()
  • you should refer to the variable "temperature" by name instead of repeating the value that was assigned to it
