While taking challenge #1 in "Using Math Methods", my solution worked but was still rejected. Why?

I'm in the course "JavaScript Basics"

script.js 
var temperature = 37.5;
var tempRoundedUp = Math.round(temperature);
alert(Math.round(temperature));
index.html 
<!DOCTYPE HTML>

Hi MaryJo,

It was rejected because you added an extra (unneeded) line of code -> var tempRoundedUp = Math.round(temperature);

If you delete that line and just leave the other two, it is correct and will pass.

Challenges are very specific. If you add more than what is asked, or deleted something that was preloaded, it will not let you pass.

Keep Coding! :)

I was not aware that the Math Method's were case sensitive, my mistake. I know now that I must use a capital "M" in the name "Math." and never a lower case "math.". Hope this helps everyone else! Happy coding.... ;)
