999*(9+9/9)+9*9/9

Hi Bobby,

Your last solution has only eight nines.

W|A didn't like that one (can't think logically, I suppose).

M first said "General::ovfl: Overflow occurred in computation", but then it gave the answer 9999 anyway.

Hi;

Yes, it did look like there were only 8 nines there. I changed it.

He was right to say overflow but of course yours is right too.

I have the result, but I do not yet know how to get it.

9(9-9+9999/√9/√9)=9999

9999 occurrs in the 999999999 we are using.

9*9=81 (2 nines)

81*99=8,019 (4 nines)

8,019+(99*9)=8,910 (7 nines)

concat(8+1,9+0),(9,9) (9 nines)

Horray! 9,999 using 9 nines!
