That is very nice to hear!

kl. yay thanks to ganesh and the other mods i now know what the stupid little ! means!

Devantè · 2006-10-05 07:31:47

OK. What is 5!!?

Maybe that's too hard for you - That would be 125! which would take you ages to figure out when you don't know how to approach something like that.

Maybe 3!!.

Remember - 3 ---> ! ---> !.

i know what it is...

3! is 3x2x1 which is 6

5! is 5x4x3x2x1 which is 120 and it isnt 125 because 5x4=20x3=60x2=120

6! is 720

7! is 2160

Devantè · 2006-10-05 08:00:38

Yes, my mistake with the 125.

What is the point in writing the 7!?

What is 3!!, though?

Devantè · 2006-10-05 08:01:52

And 5!! is not 120.

Patrick · 2006-10-05 09:09:20

Well, if you need some pratice with multiplying integers, go ahead and calculate 120!

Devantè · 2006-10-05 17:41:45

120! = 6.68950291 × 10^198

5!! = 15.

Ugh, I've forgotten the rule for double factorials. >_>

Devantè · 2006-10-09 20:33:51

Wait a second, I'm still not sure about that.

I'm 80% certain that 5!! = 125!, and 5!! ≠ 15. Or maybe I'm getting confused with something else.

espeon · 2006-10-10 03:06:29

wait a sec. if you did 5!! wouldnt that mean you would have to ! the answer to 5! which is 120 so then it would have even more digits than 100! has. AAAAAAAAAAA THIS DOESNT MAKE SENSE!

Devantè · 2006-10-10 03:21:38

Yes, it's 120. I keep getting confused with remember 5! and 5². Maybe a better way is needed to remember them, perhaps?
