Nine figures simply means a number that is written with nine digits, such as 100,000,000. If it was arrived at by adding up other numbers, then it is a sum. For example, 50,000,000 + 50,000,000 = 100,000,000

The sum of four and five is nine.
Just area. Since there is no available term for the sum of the areas of all surfaces of a figure, we call that area of the "irregular" figure.
subtract any number form nine and then with that answer and the number you subtracted 9 with, those added, make the sum of nine

'Enneahedron' - a solid figure with nine faces
It is called a nonagon. There currently is no official name for a nine-sided polygon. However, two names have been proposed for such a figure: the first is a Nonagon; the second is an Enneagon.

First, figure out what its about. Then use a few words to sum up the subject matter. And that's it! :)
The sum of (eight and nine tenths) plus (nine and eight tenths) is (eighteen and seven tenths). 8.9 + 9.8 = 18.7
If the sum of the digits of a given number equals nine or a multiple of nine, nine is a factor of that number.
