This is fantastic material. I'm going to present this quandary to my kids. Some of my kids struggle at math, so it will help them understand that math is a language and, like any language, it has abbreviations that sometimes lead you down a confusing path until you spell out more. Some of my kids are good at math and it will help them relate with others.
