parseFloat() won't work because your string begins with a non-number, the dollar sign.

You can simply do a replace to remove the dollar sign, along with a parseFloat to get the value:

totalAssets = parseFloat(totalAssets.replace('$', ''));
totalLiabilities = parseFloat(totalLiabilities.replace('$', ''));

var difference = '$' + (totalAssets - totalLiabilities);

This code replaces your original strings with floats. You could load them into new variables as well. Likewise, difference does not have to have the '$' prepended.
