Any ideas?

anonymous · Answer

none at all! haha super confused...

jim_thompson5910 · Answer

There are 5 choices for the first slot
4 for the second
3 for the third
2 for the fourth
and 1 for the fifth

So there are 5! = 5*4*3*2*1 = 120 different ways to arrange the writings

anonymous · Answer

I don't get it though hahaa

jim_thompson5910 · Answer

Remember that n P r uses factorials

It turns out that n P n = n!

So 5 P 5 = 5!
