A teacher had requested an explanation after a student had posed the question: "How would I do multiple carried numbers when more than one line is needed? He then submitted the sample problem (which I submitted to you). Evidently the student was concerned when asked to show steps to a solution and was confronted with how to show additional carried lines. The teacher had said the student had a page of 3 and 4 place numbers to be multiplied. They had studied the textbook "Introduction to Braille Mathematics" and found no solution and so posed the question to me. I suggested the format which I conveyed to you for your opinion. Basically, I just needed your input as to the correctness of my response to the teacher/student.
