On your choice.

It will return NaN (Not A Number)

width * numOfDivs === NaN

parseInt(width) * numOfDivs === 1900

or

parseFloat(width) * numOfDivs === 1900

will convert your string "190px" in to the number. So one and only thing you need to do is to convert string in to the number.

parseInt and parseFloat will not convert to the number the string in to the number if the string begin with a not a number value and it will throw away all numbers after the letter:

parseInt("a12345") === NaN
parseInt("!12345") === NaN
parseInt("123a!b45") === 123

There is a regular expression if you need to get all numbers but this task is about parseInt and parseFloat only.
