In NMF Weekly Issue #23, Jonathan asks why James' method for doing subtraction is a bit weird! (You can see the method at work here or here on YouTube.) You won't be surprised to hear that James LOVES thinking about why and how we do math, and if there might be an easier way to do things. Try James' method of subtraction for yourself and see if you find it useful!
