"May I suggest a more tactile solution, then? I cannot help with the identification of notes or anything like that, I'm afraid, but perhaps objects might be more useful in displaying calculations than paper?" Kyo wasn't sure if this actually solved anything besides the method of showing an answer, but perhaps it would be of some use. "I know that many people incorporate the use of kinetic learning aids into math curricula, and I have read of situations where an arrangement of small objects can be accepted as an answer rather than an imaginary visual figure. I'm not sure what to do about other thought processes regarding known calculations in one's mind, but maybe it would be best to explain the situation to the housekeeper when she returns."
