## 777, 888 and 999

You are given the numbers 777, 888 and 999. Using the numbers once and adding, subtracting, multiplying or dividing, how can you make 999?

(7 x 7 x 7) + (9 x 9 x 8) + ((9 – 8) x 8) = 999
(77 + 7) + 888 + (9 + 9 + 9) = 999

If other operators were allowed, another solution would be 999 modulo (888 x 777). I’m sure there are more solutions.

888+77+7+9+9+9=999
it’s very easy but so boaring in solving.

Dhet…!!!
I is such a simple queation and most are off track.
As per the N theory of existance and non existance. Like N=Z, just differentiated by angle of viewing.
So 7 = 1
and 777=111
888 + 111= 999.

Who has read the N theory by BDK.

And the persons with the complex lochas of mathematics who could find relation to the above calculations can easily figure out the simplicity and easyness of the n theory.
