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

Hey Sam,

You'll first want to remove the single quotes around parseInt(width). By placing quotes around the function call, you're turning it into a string. Lastly, numOfDivs holds an integer value, you can use that variable without parsing it.

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