The answer is 100 with no quotes around it. Nowhere in the question do they ask you to add a string, they say "store the value of 100" in the variable.

Integers don't need to be wrapped in 'quotes'. Quotes are for strings of text.

It's because you entered 100 as a string not an integer. Strings have single or double quotes around them integers do not.

Thanks, it was just confusing because of the previous question - "Which of the following is an example of a string?" the correct answer was C '1800' using quotes. I get it, I am just saying the quiz could be a little more helpful because it doesn't let you know why it was incorrect.

Thank you, I understand, but the question in the quiz said to add the "string value of 100 to the variable name score" in the previous question the correct answer from the multiple choice for a proper string was '1800' in quotes...

So like this...?

score += '100';

It was a fill in the blank ie: "var score = ____________"

I just think it would be a lot more helpful if the correct answer would be shown if I give an incorrect answer.
