Does someone understand where the parsInt should be put in relation to width?

I did not see this combination demonstrated.

app.js
var width = '190px';
var numOfDivs = 10;
var totalWidth = width * numOfDivs;

Right now width is a string. But we want it to be an int so we can multiply it by the number of divs. We take the width and send it into a function/method called parseInt. Then we multiply. Take a look here:

var totalWidth = parseInt(width) * numOfDivs;

I forgot the "e" in "parseInt". Lovely. Thank You!
