It wants you to display only, not to change the variable. You can put the Math... function inside the parentheses of the alert function.

The issue is that you have redefined your variable temperature to the result of the expression of Math.round(). The first value is 37.5, you then redefine it to become 38. You then take the Math.round(38), which obviously results in 38 again. Giving them different names would help, and also clarify your code.

  var temperature = 37.5;
  temperatureHigh = Math.round(temperature);
  console.log(temperatureHigh);
  temperatureLow = Math.floor(temperature);
  console.log(temperatureLow);
