Test yourself – Whether you are genius

Can you get a result of twenty using a single number three times? But there is small restriction in this. The number chosen must be less than 11. Of course you have the liberty of using any mathematical operator.
Wait before starting this test is to find whether you are very good or genius. Want to know how!!!!!!!
If you could suggest at least 3 methods for the achieving the above scenario you are very good
If you could do more than three then you could claim as genius.
Now start the process!!!!!!!!!!!!!!

here are the solns for ur question,

1. 5 *5 - 5
2. 4 * 4 + 4
3. 22 -2
4. 10 (log 10 *10)
5. (10 +10) log 10

4*4+4
5*5-5
2^2*2^2+2^2
22-2

6! ----- 6 * 6

Goutham,

i think u make a mistake...
actually the answer is ...

6! / (6*6) = 20

I actually meant the same 6! / 6*6 = 20 but when I typed in I did so in 2 lines
6!
---- = 20
6*6
and it defaulted it to a single line (6! --- 6*6)..

Thanks,
