display the temparature variable rounded downward to the nearest integer (hint: down is toward the "floor".)

I'm not exactly sure what's wrong with my code, can anyone elaborate what I did wrong?

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

Try entering your answer without making your alert boxes variables.

Oh, haha I got kind of confused I passed the exercise with

var temperature = 37.5 var temperature = alert(Math.round(temperature)); var temperature = alert(Math.floor(37.5));

and it worked but, yeah I realized I shouldn't even have to add the same variable towards the alerts. Thanks though!

It's only asking you to use the alert method. Since the temperature variable has been created, you don't need to create it again.

Try this, I've removed "var temperature =" from the second and third lines. You should notice that alert still functions without being assigned to the temperature variable.

var temperature = 37.5
alert(Math.round(temperature));
alert(Math.floor(temperature));

Thanks for giving an elaborate explanation :), I understand now what I did wrong.
