[翻译求助] unmultiply 和 unseven 需要如何翻译?

原文如下:(Calculating 100 ÷ 7 is really just asking what number of sevens makes a hundred.) Or, perhaps more suggestively, how do I “unmultiply” 100 by 7? ……( To undo multiplication by 7, we divide by 7. Or, as we’ve seen, we can multiply by 1/7 . This means we get to make an interesting trade: instead of undoing the multiplication activity with division (i.e., the inverse activity), we undo multiplication with another multiplication! That is, we are transferring the undoing responsibilities away from the operations and over to the numbers themselves. ) Instead of unmultiplying by seven, we are multiplying by unseven.
重点的只有标黑的两句话,其他的作为理解的背景。我的翻译是:

怎样才能用7“非乘”100呢?…… 我们不再是用七的非乘运算,而是用乘以非七的方法。

unmultiply 和 unseven翻译为 非乘 和 非七,感觉不是太恰当,但又想不到更合适的翻译,希望能够得到大家的帮助和指点。
