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?

Show the answer »

(7 x 7 x 7) + (9 x 9 x 8) + ((9 – 8) x 8) = 999
(77 + 7) + 888 + (9 + 9 + 9) = 999If other operators were allowed, another solution would be 999 modulo (888 x 777). I’m sure there are more solutions.

(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.
Who has read would understand.

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.
