18 x 18 = 324 and 18 + 18 = 36
The factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, 36 No two of them add up to 23.
No simply add the digits of the numerator 3 + 2 + 0 = 5 the digits must add to 9 if 9 will divide evenly. Take 324 the digits add up to nine and nine divides into 324 exactly 36 times!
Yes it is because all of the integers of 324 add up to a number divisible by 3 (3+2+4=9). 324/3 = 108

Factors multiply. The same set of numbers won't add up to both 140 and 240, but 120 and 20 are factors of 240 that total 140.

Well, 18 and 3 (both factors of 36) add up to 21. As well, the factors 12 and 9 add up to 21.

The interior angles are 36 degrees since all 10 corners have to add up to 360 degrees. I guess the exterior angle would be 360 - 36 = 324 degrees.
Yes it is because all of the integers of 324 add up to a number divisible by 3 (3+2+4=9). 324/3 = 108
