Please be Gentle with me......

OK!
9 = 9,
and
9/9 = 1,
but WTH!!!:?
(Sq Rt 9)!.......Isn't that 3, NOT 6????? Please Explain

n! = n * n-1 * n-2 * n-3 * ....* 1

for example

4! = 4 * 3 * 2 * 1
1! = 1

By definition 0! = 1


9 + (square root 9)! + 9/9

= 9 + 3! + 9/9
= 9 + 6 + 1
=16

Interesting. I can do 21 and 22, can you?:D

No takers? Actually, once you have got the idea it becomes almost mundane up to 64. 65 is a bit challenging and now I am stuck at 67. Think I will go back to woodworking. Anybody out there more determined than I am? :oo:

I can do 6561 can you?:rolleyes:

:D

Wow, that was tough! It took me all night, but I finally cracked it!:U
I still haven't cracked 67 though... does anybody know whether it is even possible?

I tried it but couldn't do it. Sorry.

Thanks Wongo, once worked out that each 9 can be modified by symbols to make 1, 3, 6 and 9 I thought that maybe all integers could be made up with these four numbers, or something silly like that, but it appears that this hypothesis was too far fetched.:- So, again, back to woodworking!:U

What's next 9 thirded, 9 tripled or 9 minus five times four ?? :D

I agree. Squared is the power of 2. That's got a 2 in it.
