Factors are multiplied, not added. The question needs to be something like, "Which two factors of thirty add up to 11?" The answer would then be 5 and 6.

The two factors of twenty-four that add up to eleven are three and eight. When you multiply 3 by 8, you get 24, and when you add 3 and 8, you get 11.

no 11 is not a perfect number because when u add the factors the don't add up to 11
It has two factors: 1 and 11.
When the "factors" of a number are listed, the list is usually restricted to positive factors. Then there would be no answer to the question, because no group of positive numbers can add up to make zero.
The factors are 1 & 11 !
