If you didn't watch the previous video on subtracting left to right, you're missing out. All the old school geezers will teach you right to left subtraction, and it's not wrong, and sometimes it's faster, but that doesn't mean it is THE right way. We read left to right, so it behooves us to learn the alternate way. Nonetheless, this is the conventional method (right to left), so grab some eyedrops and watch if you dare.
