(9*9)+(9+9)+(9/9) = 100
(99)/(99) +9.
9 + (9/9) = 10
Eleven.
99 plus 9/9 = 100
Ninety nine divided by nine equals eleven

Yes, there are an infinite number of posibilities. Staying only with positive odd numbers, if duplicates are allowed, then five 9s and five 11s make 100. If duplicates are disallowed, then 1 + 3 + 5 + 7 + 9 + 11 + 13 + 15 + 17 + 19 = 100
(9*9)+9+9+9/9 = 100
To get 100 using five 9s, you can use the following mathematical expression: (99 + 9/9) = 100 This equation involves adding 99 to the result of 9 divided by 9, which equals 1. This gives you a total of 100 using five 9s.
11
11 with 1 remaining 100 - 1 = 99 = 9 x 11
