Hi Benoit, in JavaScript any thing(letter, number, word, sentence) in between quote marks(whether single or double) is a string. So enclosing 'parseInt(width)' and 'parseInt(numOfDivs)' within single quote marks has converted them to simple string of letters and you can't possibly multiply string of letters. All you need do is remove both of them from those single quote marks and you're good to go :)

var width = '190px'; 
var numOfDivs = 10;
var totalWidth =  parseInt(width) * parseInt(numOfDivs) ;

And you really don't need to apply the parseInt() method on the 'numOfDivs' variable since a number(integer i.e. 10) is the value of the variable. You only need to apply the parseInt() method when you want to extract a number from a string e.g. '359horses'.
