Numbers and Strings

Need to multiply the width by the numberOfDivs, before this happens I'm trying to make the strings in to integers. Any reason why my solution below keeps throwing an error?

var width = '190px'; var x = parseInt(width);

var numOfDivs = 10; var y = parseInt(numOfDivs);

var totalWidth = x * y

parseInt takes two arguements: first is a String, and it's required , and second is a numeral system.

in var numOfDivs = 10 ,

numOfDivs is an integer , therefore you can't parse it, just pass it as a variable ( y = numOfDivs);

the solution was

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