Hey madarauchiha, You were able to use the correct method Math.floor however, for the first challenge, you applied the rounding to the temperature variable. Meaning that when you used the Math.floor method onto the variable temperature you are applying it to the rounded value, not the original, which would be 38 in this case instead of 37.5.

var temperature = 37.5;
// alerts with the rounded value of 38
alert(Math.round(temperature));
// uses the method onto the original 37.5 value and outputs 37
alert(Math.floor(temperature));

Hope that helps!
