Oh dear, Kurumi hadn't expected Professor Hadley to get so excited about her answer. It was rather silly of her to think so, Kurumi not the professor, since she knew that the Arithmancy professor loved numbers. If she didn't, why else would she teach in this field? It seemed that what she needed to do when thinking about these number combinations was take the meaning of the numbers literally. No over analyzing for this lion if she could help it

"Whenever a witch or wizard tries to touch the box or perform a spell on it, the spell will be activated," Kurumi asked, feeling a bit more confident with this answer. "Professor, one of the properties of seven is solitude...does that mean that if a witch or wizard were to attempt to open the box with someone else that the spell would react differently? Or...if the one trying to open the box had their own type of magic?" She hoped that the wording on the latter part was obvious enough to get her point across?

Yep, she was still holding out for some special guests this lesson.
