Hmm. There is a bit more math than adding 3 numbers together. (had I known that, I would not have
bought this product) It is not difficult. but for me it ruins the flow. and becomes something
reminiscent of a classic math trick most people know from their school days. I actually think it is
misleading to write that there are a few more steps (instead of writing that there is a little more
math than adding 3 numbers together) and for that reason i give it 2 stars.
