Determining whether two addresses are on the same subnet formula
In addition to Martin's correct answer regarding appllication of the formula you cited, you may also want to consider a tool that you can run for this. Solarwinds offers a free (ad-supported) version of their Subnet Calculator that you can download to your desktop. Here is a link to it. It's also included (without ads) in their paid Engineer's Toolset product.
Of course there are also web sites with tables and such.
