Question

Use as many as mathematical operators to get 84 using only 9 and 6 ;)

i.e u can apply operator on/using 9 and/or 6.

Just these two numbers ...... and any mathematical operator.

Ranks:

No. of

operators ............RANK

used

1 ..................Genius B))

2 ..................Extra ordinary :lol:

3 ...................Intelligent :P

4....................Very good :D

5....................Nice ;)

I'm average.

Actually, I think I might REALLY need some attention:

6+6+6+6+6+6+6+6+6+6+6+6+6+6=84

:o :o :o
9*6+6+6+6+6+6=84
:mellow:

the 13 operator one doesn't contain 9s.

[spoiler=Ok we take it other way round ;) ]

What is the Maximum number of operators that can be used to get 84

and using only 9 and 6.

but wudnt the maximum number of operators be infinite ..

9*6+6+6+6+6+6+6-6+6-6+6-6.........infinity

How can it be infinity.

Some where we have to get the 84 which we want.

1 question: Do you limit us to use only ONE 9 and ONE 6 or can be more?

:huh:

No there is no limit to the Use of 9s and 6s

You can use them as many as you want.

No there is no limit to the Use of 9s and 6s

You can use them as many as you want.

So the maximum answer can be infinity

(9/9) + (6/6) + (9/9) + (6/6) + ....

for 84 times, as each (9/9) and (6/6) equals to 1, after 84 times it becomes 84

however, if then the minus sign come in each time -1 then + 1 then -1 then +1

it will be

+ .......... - (9/9) + (6/6) - (9/9) + (6/6) ......... and it can continues.....

Max number of operators that can be used to get 84 is infinity...

Becoz

9*6+6+6+6+6+6 =84

After this we can keep on adding n subtracting 6 or 9 from it (+6-6) for as long as we want .... and the answer wud still be 84.
