That's so clever! I rarely showed my thinking or working out scribbles, so the teacher assumed I was cheating and marked me wrong until I convinced her I was doing it in my head. Then she told me I still had to write down how I worked it out. :(
It wastes time and leads to mistakes when one has to break a simple one-step problem into three steps, and then write out each one.
