Numbers
Numbers are our way to quantify, label, and organize the world around us in a logical manner. However, the systems used to obtain this goal differ geographically, historically, and by relative utility. All questions pertaining to numbers, including historic labeling systems, bases of numerical systems, constants, and the various ways they're grouped together, should be placed into this category.

What are the 9 numbers under a hundred with an odd number of factors?
Eight of them are the squares of 2 to 9: 4, 9, 16, 25, 36, 49, 64, 81.
Not sure that 12 = 1 should be included in the list as the 9th number.
Another contributor had no such reservations:
1, 4, 9, 16, 25, 36, 49, 64, 91.
And 100 would be the tenth one.
'1' certainly satisfies the specifications in the question.
