I get a well done, I'm doing great and this is completely wrong. Teamtreehouse please fix, and what am I doing wrong?

If I select "Check Work", I get a job well done. however, on challenge task #2 I get an error telling me to check Task #1. MDN isn't helping either. Just a page with a bunch of code that I do not understand. Can anyone explain in "code" why the 37.5 doesn't round to 38 and how to use the Math.floor along with the alert and temperature variable. In code, please and thank you.

script.js
var temperature = 37.5;
Math.round(temperature);
alert(temperature);

Your code rounds the value, but doesn't store it anywhere. Then the alert just shows the original value. So combine these lines together to show the rounded value:

alert(Math.round(temperature));

Then leave that line as is and add another one like it (but with a different function) for task 2.
