Imagine you have 10 <div> tags on a web page. Each div is 190 pixels wide. Using the two variables in this script, create a new variable named totalWidth that multiplies the width by the numOfDivs variable. Because the width variable is a string, you'll need to use a JavaScript function to retrieve the number value.
var width = '190px';
var numOfDivs = 10;
var totalWidth = '190px' *-(10);

The big clue in this challenge is the line, "Because the width variable is a string, you'll need to use a JavaScript function to retrieve the number value."
This is done with the function parseInt() which will take the number out of a string and just return the number. So you'd do something like this:
var width = '190px';
var numOfDivs = 10;
var totalWidth = parseInt(width) * numOfDivs;

that's how i solved it
