//you have to point to point to the question.

var temperature = 37.5;//
alert(Math.round(temperature)); 
var temperature = Math.floor(37.5); //why is this line
var temperature = 37.5; // why is this line
alert(Math.floor(temperature));
var temperature = Math.floor(37.5); // why is this line
alert(temperature); //37.5 // why is this line

// please take all those lines, as those have not been asked from the question.
// simple 2 alert statements
// one using Math.round
// the other using Math.floor
// do not complicate

Just remove the unnecessary lines all initialize every variable only one time

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