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.

app.js 
var width = '190px';
var numOfDivs = 10;
index.html 
<!DOCTYPE HTML>
<html>
<head>
  <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

It doesn't look like you've tried to answer yet. If you try but don't get it, the challenge checker may give you a hint that will help you solve it.

You'll start by creating a new variable (using the name they ask for), and assign it to the value you get by multiplying the other variables together. You already know you need to convert the value somehow, but if you're not sure how, try it without and see what the challenge says.

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

Watch for uppercase in parseInt.

Hi, yes I am having trouble with that problem also. Would appreciate the feedback.

var width = '190px'; var numOfDivs = 10;

var width = parseInt(width); var totalWidth = width * numOfDivs;
